The application areas for plastic optical fibers such as in-building or aircraft networks usually have tight power budgets and require multiple passive components. In addition, advanced modulation formats are being considered for transmission over plastic optical fibers (POFs) to increase spectral efficiency. In this scenario, there is a clear need for a flexible and dynamic system-level simulation framework for POFs that includes models of light propagation in POFs and the components that are needed to evaluate the entire system performance. Until recently, commercial simulation software either was designed specifically for single-mode glass fibers or modeled individual guided modes in multimode fibers with considerable detail, which is not adequate for large-core POFs where there are millions of propagation modes, strong mode coupling and high variability. These are some of the many challenges involved in the modeling and simulation of POF-based systems. Here, we describe how we are addressing these challenges with models based on an intensity-vs-angle representation of the multimode signal rather than one that attempts to model all the modes in the fiber. Furthermore, we present model approaches for the individual components that comprise the POF-based system and how the models have been incorporated into system-level simulations, including the commercial software packages SimulinkTM and ModeSYSTM.

Statistical Approach for Modeling Connectors in SI-POF Avionics Systems
The application of Plastic Optical Fibers (POF) as transmission medium in avionics systems requires the introduction of a number of connections that affect both the power budget and the system bandwidth. Additionally, the use of air-gap connectors in order to avoid fiber damage by physical contact through the vibrations induces statistically variable positional shifts that add to the already large variability present in POF based systems. Therefore, it is important to incorporate connector variability to obtain realistic simulation results of the performance of POF avionics links. Our aim here is to evaluate the impact of this variability on transmission properties by using a connector model that includes lateral and longitudinal offsets and performing Monte Carlo simulations of several avionics scenarios using a POF propagation matrix framework.

Diagnosis of neural diseases can be performed using microsystems that record neural signals collected simultaneously after neural simulations. Headstage and homecage-based recording systems can be implanted on small freely-moving animals to test such system which requires miniaturized, lightweight, and high gain antennas in order for the small animals to carry them easily while also decreasing loss during data transmission. This paper proposes a 15×15 mm2 slot antenna with a 50 Ω microstrip excitation line. The slot antenna is created by the addition of slots in the ground plane which is a common miniaturization method as it results in ultrawideband operating frequency. A lumped component-based model along with a 3D EM model of the modified SMA connector used for the measurement and headstage model is also developed to observe the effect on the antenna performance. The antenna achieved an operating frequency of 4.25 - 9.4 GHz and a bidirectional radiation pattern with gain ranging from 2.24 to 4.35 dBi. The proposed antenna is also circularly polarized and achieves 80.6% - 90.8% radiation efficiency over the operating BW. It can transmit a maximum of 20 dBm of power over the operating frequency without exceeding the FCC-imposed SAR limit. Based on the performance, the antenna is suitable for headstage and homecage-based neural signal recording systems with IR-UWB transmitter for high data rate transmission.more » « less

Polymer optical fibers (POFs) are playing an important role in industrial applications nowadays due to their ease of handling and resilience to bending and environmental effects. A POF can tolerate a bending radius of less than 20 mm, it can work in environments with temperatures ranging from −55 °C to +105 °C, and its lifetime is around 20 years. In this paper, we propose a novel, rigorous, and efficient computational model to estimate the most important parameters that determine the characteristics of light propagation through a step-index polymer optical fiber (SI-POF). The model uses attenuation, diffusion, and mode group delay as functions of the propagation angle to characterize the optical power transmission in the SI-POF. Taking into consideration the mode group delay allows us to generalize the computational model to be applicable to POFs with different index profiles. In particular, we use experimental measurements of spatial distributions and frequency responses to derive accurate parameters for our SI-POF simulation model. The experimental data were measured at different fiber lengths according to the cut-back method. This method consists of taking several measurements such as frequency responses, angular intensity distributions, and optical power measurements over a long length of fiber (>100 m), then cutting back the fiber while maintaining the same launching conditions and repeating the measurements on the shorter lengths of fiber. The model derivation uses an objective function to minimize the differences between the experimental measurements and the simulated results. The use of the matrix exponential method (MEM) to implement the SI-POF model results in a computationally efficient model that is suitable for POF-based system-level studies. The efficiency gain is due to the independence of the calculation time with respect to the fiber length, in contrast to the classic analytical solutions of the time-dependent power flow equation. The robustness of the proposed model is validated by calculating the goodness-of-fit of the model predictions relative to experimental data.more » « less

AFDX (Avionics Full Duplex Switched Ethernet) is developed to support mission-critical communications while providing deterministic Quality of Service (QoS) across cyber-physical avionics systems. Currently, AFDX utilizes FP/FIFO QoS mechanisms to guarantee its real-time performance. To analyze the real-time performance of avionic systems in their design processes, existing work analyzes the deterministic delay bound of AFDX using NC (Network Calculus). However, existing analytical work is based on an unrealistic assumption leading to assumed worst cases that may not be achievable in reality. In this paper, we present a family of algorithms that can search for realistic worst-case delay scenarios in both preemptive and non-preemptive situations. Then we integrate the proposed algorithms with NC and apply our approach to analyzing tandem AFDX networks. Our reality-conforming approach yields tighter delay bound estimations than the state of the art. When there are 100 virtual links in AFDX networks, our method can provide delay bounds more than 25% tighter than those calculated by the state of the art in our evaluation. Moreover, when using our reality-conforming method in the design process, it leads to 27.2% increase in the number of virtual links accommodated by the network in the tandem scenario.more » « less

This paper describes the Triton federated-avionics security testbed that supports testing real aircraft electronic systems for security vulnerabilities. Because modern aircraft are complex systems of systems, the Triton testbed allows multiple systems to be instantiated for analysis in order to observe the aggregate behavior of multiple aircraft systems and identify their potential impact on flight safety. We describe two attack scenarios that motivated the design of the Triton testbed: ACARS message spoofing and the software update process for aircraft systems. The testbed allows us to analyze both scenarios to determine whether adversarial interference in their expected operation could cause harm. This paper does not describe any vulnerabilities in real aircraft systems; instead, it describes the design of the Triton testbed and our experiences using it. One of the key features of the Triton testbed is the ability to mix simulated, emulated, and physical electronic systems as necessary for a particular experiment or analysis task. A physical system may interact with a simulated component or a system whose software is running in an emulator. To facilitate rapid reconfigurability, Triton is also entirely software reconfigurable: all wiring between components is virtual and can be changed without physical access to components. A prototype of the Triton testbed is used at two universities to evaluate the security of aircraft systems.more » « less
