A microwave absorber is designed with a given absorbing material whose relative permittivity and permeability are known. In this design process, impedance matching between absorber and free space is achieved by circular metal patches of predesigned shape printed periodically on absorbing material. Designed microwave absorber along with predesigned designed metal strip is modeled in 3D electromagnetic simulation software HFSS. Simulated frequency response of reflection coefficient verifies impedance matching and absorption at design frequency.

Enhancement of Relative Permittivity of Material with Metallic Inclusions – Experimental Verification
In this project, it was shown by simulation that the permittivity of a material could be enhanced by embedding metal inclusions in the host material. Later, a series of systematic experiments were carried out with free space material measurement equipment/system to demonstrate the enhancement of permittivity with circular metal patches printed periodically on a host material to validate the simulation results.

An artificial or meta material was fabricated by printing I-shaped metal patterns periodically on a dielectric host medium to demonstrate frequency blocking property. The research was conducted by 3D electromagnetic simulation software first and then verified by several experiments. Experimental results showed that center frequency of blocked band could be controlled by adjusting the size and shape of I-shaped metal patterns.more » « less

This paper presents a simulation-based study on the relative permittivity of 3D printed dielectric slabs printed with varying infill densities. In this study, a percentage volumetric model has been employed to model the infill density in a 3D printed dielectric slab. The relative permittivity of the filament material used to design the slab is assumed to be 2.45. The modeled slab is fitted into various rectangular waveguides with varying dimensions corresponding to different frequency ranges. As the infill density decreases, the relative permittivity of the dielectric slabs decreases. This lower value of relative permittivity is referred to as effective relative permittivity (εr.eff) throughout the paper. The study concludes that the effective relative permittivity of the slab decreases linearly as the infill density is decreased for the model. This study offers valuable insights into the effective relative permittivity of dielectric slabs under varying infill densities, providing implications for applications in areas such as antenna design.more » « less

The piezoelectric coefficient and permittivity of a piezoelectric material depend on the crystal structure which can be modified by an external electrical field. In this research, we aim to find out a relationship between external electrical field and the piezoelectric and permittivity properties of ZnO. The numerical analysis, finite element analysis, and experimental measurements are to be addressed in this paper. The result of this work can be a good source for the study of piezoelectric material.more » « less

Epitaxial ScxAl1−xN thin films of ∼100 nm thickness grown on metal polar GaN substrates are found to exhibit significantly enhanced relative dielectric permittivity (εr) values relative to AlN. εrvalues of ∼17–21 for Sc mole fractions of 17%–25% ( x = 0.17–0.25) measured electrically by capacitance–voltage measurements indicate that ScxAl1−xN has the largest relative dielectric permittivity of any existing nitride material. Since epitaxial ScxAl1−xN layers deposited on GaN also exhibit large polarization discontinuity, the heterojunction can exploit the in situ high-K dielectric property to extend transistor operation for power electronics and high-speed microwave applications.more » « less
