PROJECT TITLE :
Analysis of High-Frequency Electromagnetic Scattering by Complex Targets Using Dual Flat Facet Representation
It's typically difficult to cater for multiple scattering and shadowing in the applying of high-frequency asymptotic methods for electromagnetic (EM) scattering since this involves difficult geometrical computation. Efficient techniques with the use of twin flat illustration of the target geometry are proposed to beat this disadvantage. The dual aspect representation is created by a set of small triangular aspects and an additional set of comparatively large triangular sides. The set of smaller sides is used for the EM analysis therefore that approximation can be adopted to avoid the complicated geometrical computation associated with multiple scattering and shadowing, and also the set of larger facets is applied for the computation of line/aspect interaction and geometrical reflection to achieve computational potency. Numerical results are presented to demonstrate the validity and potency of the current technique, and also the impact of the aspect size on the solution accuracy is discussed.
