Abstract

Electromagnetic waves such as light has been assumed to bend around large obstacles due to gravitation. The objective of this study is to observe if the same phenomenon can be predicted from a diffraction analysis. The example chosen to illustrate this point is a PEC (perfect electric conductor) sphere located along/near the line of sight of a plane wave propagation. A PEC sphere will diffract the incident electromagnetic energy. We evaluate the scattered fields wave at a few points away from the obstacle. From the measured field points we now try to predict the DOA (direction of arrival) of the signal of interest. The simulations have been carried out using WIPL-D and the DOA estimation is done by using the Matrix Pencil Method. The result shows some interesting trends!.
