Matlab-Based Virtual Wedge Scattering Tool for the Comparison of High Frequency Asymptotics and FDTD Method
Keywords:
conformal FDTD, Dey-Mittra, FDTD, hard boundary condition, high frequency asymptotics, scattering, soft boundary condition, staircase modeling, wedge diffractionAbstract
A novel Matlab-based diffraction tool for the investigation of scattered fields around a two-dimensional Perfectly Electric Conductor (PEC) wedge is introduced. Analytical (Exact by Integral, as well as some High Frequency Asymptotic (HFA) techniques) and numerical (Finite-Difference Time-Domain (FDTD)) models are included. The FDTD staircase modeling problems are removed by the application of Dey- Mittra Conformal approach.
