Field Enhancement in a Grounded Dielectric Slab by Using a Single Superstrate Layer
The addition of a dielectric layer on a slab configuration is frequently utilized in various electromagnetic devices in order to give them certain desired operational characteristics. In this work, we consider a grounded dielectric film-slab, which is externally excited by a normally-incident Gaussian beam. On top of the film-slab, we use an additional suitably selected single isotropic superst...
متن کاملArtificial 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...
متن کاملSurface Waves Propagating on Grounded Anisotropic Dielectric Slab
This paper investigates the characteristics of surface waves propagating on a grounded anisotropic dielectric slab. Distinct from the existing analyses that generally assume that the fields of surface wave uniformly distribute along the transverse direction of the infinitely large grounded slab, our method takes into account the field variations along the transverse direction of a finite-width ...
متن کاملEfficiency Enhancement of Si Solar Cells by Using Nanostructured Single and Double Layer Anti-Reflective Coatings
The effect of single and double-layer anti-reflective coatings on efficiency enhancement of silicon solar cells was investigated. The reflectance of different anti-reflection structures were calculated using the transfer matrix method and then to predict the performance of solar cells coated by these structures, the weighted average reflectance curves were used as an input of a PC1D simulation....
متن کاملEnhancement 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 ...
