A simple analytical model based on the transmission matrix approach is proposed for equivalent wire medium (WM) interfaces. The obtained ABCD matrices for equivalent interfaces capture the non-local effects due to the evanescent transverse magnetic (

Mushroom-type structures with the wires connected through diodes: electronically tunable properties

Autor: Chandra S. R. Kaipa, Alexander B. Yakovlev

Publikováno v: 2014 IEEE Antennas and Propagation Society International Symposium (APSURSI).

Here, we study the reflection and transmission characteristics of mushroom-type structures with the diodes inserted at the center along the direction of the wires. The analysis is carried out using the nonlocal homogenization model for the mushroom s

We report on the dual nature (capacitive and inductive) of the surface impedance of periodic graphene patches at low-terahertz frequencies. The transmission spectra of a graphene-dielectric stack shows that patterned graphene exhibits both the low-fr

In this paper, we establish a general formalism to quantify the interaction of electromagnetic waves with mushroom-type structures (high impedance surface and bi-layer) with diodes inserted along the direction of the wires. The analysis is carried ou

Here, we report on the transmissivity of electromagnetic waves through a stack of monolayer graphene sheets separated by dielectric slabs at low-terahertz frequencies. It is observed that the multilayer structure possesses band-gap properties and sup
