Efficiency improvement with a recursive Taylor expansion of Bessel functions for layered media Green's function

This paper demonstrates the performance of a novel interpolation technique for computing the impedance matrix with a layered media Green's function (LMGF). The interpolation technique is based on a recursive Taylor expansion of a Bessel function of arbitrary order. Numerical simulation of microstrip array antennas embedded in a multi-layer medium is performed and the performance of the interpolation technique is demonstrated.
