Asymmetric modes suppression in Cerenkov device using anisotropic media

open access: yesAIP Advances, 2019
Asymmetric modes competition in Cerenkov devices were studied with a view to developing a novel method to suppress modes competition, based on loading of the slow-wave structure (SWS) with an anisotropic medium.

A Graded Partial Dielectric Transformer for Bandwidth Enhancement in an Ultrawideband High-Power Combined TEM Antenna

open access: yesTelecom
Designing an ultrashort, fast-rising high-power microwave (HPM) system requires an antenna that simultaneously provides ultrawideband (UWB) operation, high gain, and megawatt-level power handling under strict size, weight, and power (SWaP) constraints ...

A New Method to Calculate Induced Current of Thin Wire over Anisotropic Ground under HPM

open access: yesInternational Journal of Antennas and Propagation, 2019
The time response analysis of wire structures is often carried out in free space or isotropic half-space, but the real ground is usually layered and has anisotropic properties.
