Abstract :
A simple, fast, and accurate analytical method is introduced to obtain the EM scattered fields due to an infinite circular cylinder buried in a homogeneous dielectric half-space, illuminated by a normally incident transverse magnetic (TM) plane wave. The method is applied to perfect electric conducting (PEC) and dielectric cylinders of complex permittivity with the host dielectric medium being lossy or lossless. The accuracy of this method is verified using a finite-difference time-domain code (FDTD) on a wide frequency range and the results are presented discussing the range of validity of this approach.
