Wideband Electromagnetic Analysis of Finite- Conductivity Cylinders

On the wideband EMI response of a rotationally symmetric permeable and conducting target

A simple and accurate model is presented for computation of the electromagnetic induction (EMI) resonant frequencies of canonical conducting and ferrous targets, in particular, finite-length cylinders and rings. The imaginary resonant frequencies correspond to the well known exponential decay constants of interest for time-domain EMI interaction with conducting and ferrous targets. The results ...

Static Analysis of Orthotropic Functionally Graded Material Cylinders with Finite Length by a Mesh-Free Method

In this paper static analysis of orthotropic functionally graded material (FGM) cylinders with finite length was carried out by a mesh-free method. MLS shape functions are used for approximation of displacement field in the weak form of equilibrium equation and essential boundary conditions are imposed by transformation method. In this simulation, an ax symmetric model is used. Mechanical prope...

Speeding up the Stress Analysis of Hollow Circular FGM Cylinders by Parallel Finite Element Method

In this article, a parallel computer program is implemented, based on Finite Element Method, to speed up the analysis of hollow circular cylinders, made from Functionally Graded Materials (FGMs). FGMs are inhomogeneous materials, which their composition gradually varies over volume. In parallel processing, an algorithm is first divided to independent tasks, which may use individual or shared da...

Time-Domain Full-Wave Analysis and System-Level Modeling of Microwave Ultra-Wideband Indoor Communication Systems

Ultra-wideband radio is an enabling microwave technology for broadband communication and high-resolution sensing. However, the full realization of its potential requires further research on ultra-wideband signal propagation and interference with existing narrowband systems. Such questions can be rigorously resolved from the fundamental viewpoint of electromagnetic theory. Yet, this approach has...
