A Cwa-based Detection Procedure of a Perfectly-conducting Cylinder Buried in a Dielectric Half-space

The electromagnetic scattering problem of a short-pulse plane wave by a perfectly-conducting circular cylinder, buried in a dielectric half-space, is solved by means of a cylindrical-wave approach (CWA). The incident plane wave may have a rather general shape in the time domain. The technique is applicable for arbitrary polarization, for any cylinder size and burial depth, and it gives results ...

TM Electromagnetic Scattering from Multilayered Dielectric Bodies – Numerical Solution

An integral equation approach is derived for an electromagnetic scattering from an M multilayered dielectric domain. The integral equation is valid for 2D and 3D Helmholtz equation. Here we show the numerical solution for the 2D case by using the Nyström method. For validating the method we develop a mode matching method for the case when the domains are multilayered circular cylinders and give...

Electromagnetic Scattering from a Perfect Electromagnetic Conductor Cylinder Buried in a Dielectric Half-space

An analytical solution is presented for the electromagnetic scattering from a perfect electromagnetic conducting circular cylinder, embedded in the dielectric half-space. The solution utilizes the spectral (plane wave) representations of the fields and accounts for all the multiple interactions between the buried circular cylinder and the dielectric interface separating the two half spaces.

Time-Domain Analysis of TM Scattering from Conducting Cylinders Using a Hybrid Method

In this paper, the finite-element method (FEM) is used to solve open-region problems utilizing the time-domain differential form of Maxwell’s equations. The radiation boundary condition for the open-region problem is enforced through the time-domain Green’s function as used in integral-equation methods, yet keeping the sparsity of the FEM matrices. In this paper, the proposed method is applied ...
