Conventional techniques to compute Green's functions using a spectral representation, based on real-axis integration of spectral integrals, often produce slow convergence in environments exhibiting stratified inhomogeneity. Here, we present a novel methodology to guarantee exponential-cum-algebraic convergence of the computed time-harmonic electromagnetic fields that are produced by either electric or (equivalently modeled) magnetic dipoles in such media. In particular, we address the more… CONTINUE READING
