چکیده

Abstract—The scattering of electromagnetic waves from a Frequency Selective Surfaces (FSSs) composed of a new oneand two-turn square spiral shaped periodic structures are investigated by using modal expansion method for a linearly polarized transverse electric (TE) and transverse magnetic (TM) incident waves. The Moment Method (MM) of Galerkin type is employed by expressing the current induced on the metallic surfaces in terms of Piecewise Sinusoidal (PWS) basis functions to determine the FSS structure reflection and transmission coefficients.

Artificial magnetic conductors realised by frequency-selective surfaces on a grounded dielectric slab for antenna applications

New designs of artificial magnetic conductors (AMC), including hard and soft surfaces and dual-polarised high-impedance surfaces are realised by printed dipole/slot frequency-selective surfaces (FSS) implemented on a grounded dielectric slab. Multiband designs of hard and soft surfaces are proposed based on the use of FSS structures with different resonance lengths and orientation of dipoles/sl...

Enhancement of Inset Feed Microstrip Semicircular Patch Antenna Directivity using Dielectric Superstrate

The subject of enhancing microstrip patch antennas directivity, using either a frequency selective surface (FSS) or a double-negative (DNG) metamaterial slab, has been investigated by a number of researchers in recent years. The purpose of this paper is to show that we can also achieve the same goal by using a much simpler design for the superstrate, namely a dielectric slab, whose performance ...

Potential Calculations for Arbitrary Initial Conditions and Capacitance of Arbitrarily Shaped Capacitors

When electric potential is applied to conductors an electric field is created, which in turn creates arbitrary potentials between conductors. This is a study of the potential, electric field and charge involved in conductors. This also discusses capacitance of arbitrary conductors and how that is related to charge. Specifically this will discuss a concentric square cylinder capacitor like that ...

Transparency of overdense plasma with V shape density profile

In this study, we investigate the transparency of an overdense inhomogeneous plasma slab. This anomalous transmission is achieved when the conditions provided for the incident electromagnetic wave to excite coupled surface waves on the both sides of the slab. These conditions require that the homogeneous overdense plasma, or the metallic film, is placed between two dielectric layers. Here, the ...

A Photomixer Driven Terahertz Dipole Antenna with High Input Resistance and Gain

A terahertz (THz) antenna is proposed that offers high input resistance and gain in the presence of an electrically thick GaAs substrate. The antenna is centrally fed using two vertical probes connected to a photomixer on a thin low temperature grown gallium arsenide (LTG-GaAs) film which is supported by the GaAs substrate. An input impedance of ∼ 3.3 kΩ has been achieved using a dipole antenna...
