This paper presents the design and fabrication of a Compressive Reflector Antenna (CRA) for high-sensing-capacity millimeter-wave imaging applications. The CRA is fabricated using additive manufacturing or 3D printing and metalized by applying silver conductive coating spray on its surface. The near-fields of the CRA are measured when it is fed by a conical horn antenna, a compressive horn antenna, and a perturbed cavity.The singular value distribution and sensing capacity of the CRA fed by the aforementioned antennas are calculated and compared.

High Capacity and Efficiency Optimization of Compressive Antennas for Imaging Applications
Compressive Reflector Antennas (CRA )have been shown to provide enhanced imaging capabillities over Traditional Reflector Antennas (TRA) when compressed sensing (CS) techniques are employed. This paper presents a novel method for designing dielectric CRA’s for high sensing capacity imaging applications.In the design procedure, the dielectric constants of scatterers added to a TRA are optimized in order to maximize the capacity and efficiency of the imaging system’s sensing matrix. Numerical results are presented that demonstrate the method’s ability to enhance the CS reconstruction capabilities of the CRA.

This paper describes a new coded interferometric system for sensing the physical temperature radiated from the Earth’s surface. The proposed system consists of a Compressive Reflector Antenna (CRA) coated with Metamaterial Absorbers (MMA). The CRA and the MMA are used to code the received electromagnetic field in space and in frequency, at the focal plane array. The MMA is modeled by an equivalent magneto-dielectric medium having a definite thickness. A high frequency method based on Physical Optics is used to build the sensing matrix of the system, and the inverse problem is solved using a Nesterov-based Compressive Sensing methodology. Numerical examples are carried out in order to reconstruct the physical temperature of the Earth’s surface. The performance of the proposed system is compared to that of the conventional interferometric system GeoSTAR. Preliminary results show that the metamaterial-based CRA provides comparable performance to the GeoSTAR configuration with only half of the feeding elements, while keeping the same physical aperture size for the two configurations.more » « less

We propose a field-based design for dielectric antennas to interface diamond color centers in dielectric membranes with a Gaussian propagating far field. This antenna design enables an efficient spin-photon interface with a Purcell factor exceeding 400 and a 93% mode overlap to a 0.4 numerical aperture far-field Gaussian mode. The antenna design with the back reflector is robust to fabrication imperfections, such as variations in the dimensions of the dielectric perturbations and the emitter dipole location. The field-based dielectric antenna design provides an efficient free-space interface for closely packed arrays of quantum memories for multiplexed quantum repeaters, arrayed quantum sensors, and modular quantum computers.more » « less

End-to-end data-driven image compressive sensing reconstruction (EDCSR) frameworks achieve state-of-the-art reconstruction performance in terms of reconstruction speed and accuracy. However, due to their end-to-end nature, existing EDCSR frameworks can not adapt to a variable compression ratio (CR). For applications that desire a variable CR, existing EDCSR frameworks must be trained from scratch at each CR, which is computationally costly and time-consuming. This paper presents a generic compression ratio adapter (CRA) framework that addresses the variable compression ratio (CR) problem for existing EDCSR frameworks with no modification to given reconstruction models nor enormous rounds of training needed. CRA exploits an initial reconstruction network to generate an initial estimate of reconstruction results based on a small portion of the acquired measurements. Subsequently, CRA approximates full measurements for the main reconstruction network by complementing the sensed measurements with resensed initial estimate. Our experiments based on two public image datasets (CIFAR10 and Set5) show that CRA provides an average of 13.02 dB and 5.38 dB PSNR improvement across the CRs from 5 to 30 over a naive zero-padding approach and the AdaptiveNN approach(a prior work), respectively. CRA addresses the fixed-CR limitation of existing EDCSR frameworks and makes them suitable for resource-constrained compressive sensing applications.more » « less

This paper explores the use of compressive sensing (CS) methods to microwave-induced thermoacoustics (TA)imaging. Moreover, it proposes the use of a holey cavity as a mechanism to enhance the reconstruction properties of the sensing matrix. The CS imaging and the holey cavity reduce the number of measurements needed to perform the imaging, thus reducing the overall complexity of the imaging system.more » « less
