Multiresolution Time-Domain Analysis of Plane-Wave Scattering From General Three-Dimensional Surface and Subsurface Dielectric Targets
The multiresolution time domain (MRTD) is used to analyze wide-band plane-wave scattering from general dielectric targets embedded in a lossy half-space, with free-space scattering as a special case. A Haar wavelet expansion is used for simplicity, this constituting a generalization of the widely used finite-difference time-domain (FDTD) method. In addition to developing the mathematical formul...
متن کاملModelling of Dielectric Cavity Structures Using Multiresolution Time-domain Analysis
Multiresolution time domain (MRTD) analysis is applied directly to Maxwell’s equations to model inhomogeneous dielectric material. In our approach, scaling and wavelet functions are used as a complete basis for the method of moments. The MRTD scheme is used to analyze different types of resonant cavity structures with varying dielectric perturbations in one, two and three dimensions. The result...

متن کاملNumerical Analysis of Electromagnetic Scattering from a Dielectric Rough Surface Cylinder
1.Introduction The wave scattering from rough surfaces is an important problem which closely relates to the measurement technology or diagnosing techniques by using microwave, millimeter wave, light wave or acoustic wave (1). Various kinds of theoretical models and methods for analyzing the wave scattering from random rough surfaces have been proposed so far. However, they have often used appro...
متن کاملA Hybrid Method of Scattering from a Dielectric Target above a Rough Surface: Te Case
A hybrid method, combining analytic Kirchhoff approximation (KA) and numerical method of moments (MoMs), is developed to solve the two-dimensional (2D) scattering problem of a dielectric target with arbitrary cross section above a moderate perfect electric conductor (PEC) rough surface under TE-polarized tapered wave incidence. The induced current on the rough surface is analytically expressed ...
