Resonance Scattering by a Circular Dielectric Cylinder

Radio Science, Volume 56, Issue 6, June 2021., 2021
Abstract A unified approach is developed for the analysis of singularities of the scattered field and vanishing of scattering harmonics. Rigorous proofs are presented of the existence of complex resonance singularities of the solution to the problem of the plane wave scattering by a circular homogeneous dielectric cylinder.

A single‐layer high‐gain dipole antenna array with a bidirectional radiation pattern based on parallel‐strip line

IET Microwaves, Antennas &Propagation, Volume 15, Issue 3, Page 323-331, 26 February 2021., 2021
Abstract A single‐layer dipole antenna array with quasi‐Yagi configuration has been proposed and demonstrated, which provides a dual radiation pattern with the same sense. This antenna is mainly composed of a substrate‐supported parallel strip line (PSL) and several periodic dipole elements.

Leaky Wave Array in Full Planar Substrate with EBG‐Based Wave Guiding Channel

International Journal of Antennas and Propagation, Volume 2021, Issue 1, 2021., 2021
A new type of wave guiding structure is proposed is this paper. The guiding channel is developed on the full planar dielectric substrate and aligned with electromagnetic bandgap (EBG) units. Since the bandgap of these mushroom‐like units is calculated with a coverage of the channel working band, these units are of great importance on ensuring the ...

THZ POWER DIVIDER CIRCUITS ON PLANAR GOUBAU LINES (PGLS) [PDF]

Progress In Electromagnetics Research C, 2012
Terahertz spectroscopy is a new tool for real time biological analysis. Unfortunately, investigations on aqueous solutions remain difficult and need to work on nanovolumes. Integrated Terahertz instrumentation remains a challenge. We demonstrate that Planar Goubau Line (PGL) technology could bring a real practical solution to reach this goal.

No genetic evidence for involvement of Deltaretroviruses in adult patients with precursor and mature T-cell neoplasms [PDF]

, 2007
Background The Deltaretrovirus genus comprises viruses that infect humans (HTLV), various simian species (STLV) and cattle (BLV). HTLV-I is the main causative agent in adult T-cell leukemia in endemic areas and some of the simian T-cell lymphotropic ...

Capacitively-Coupled Resonators for Terahertz Planar-Goubau-Line Filters

IEEE Transactions on Terahertz Science and Technology, 2023
Low-loss planar Goubau lines show promising potential for terahertz applications. However, a single-wire waveguide exhibits less design freedom than standard multi-conductor lines, which is a significant constraint for realizing standard components.
