abstract = {<p style="text-align: justify;">The dyadic Green&#39;s function in multi-layer structures for Maxwell equations
is a key component for the integral equation method, but time consuming to calculate.
A novel algorithm, the Fast Interpolation and Filtering Algorithm (FIFA), for the calculation
of the dyadic Green&#39;s function in multi-layer structures is proposed in this
paper. We discuss in specific details, ready for use in practical calculations of scattering
in layer media, how to apply FIFA to calculate various components of the dyadic
Green&#39;s function. The algorithm is based on two techniques: interpolation of Green&#39;s
function both in the spectral domain and spatial domain, and low pass filter window
based acceleration. Compared to the popular Complex Image Method (CIM), FIFA
provides the same speed and overcomes several difficulties associated with CIM while
being more general and robust. Specifically, there are no limitations on the frequency
range, the number of layers in the structure and the type of Green&#39;s functions to be
calculated, and moreover, no need to extract surface wave poles from the spectral form
of the Green&#39;s function. Numerical results are given to demonstrate the efficiency and
robustness of the proposed method.</p>},
