Abstract

Dielectrics Discrete Complex Image Method (DCIM) Frequency Green's function methods Interpolation method of moments (MoM) Microstrip Microwave devices Moment methods multilayered Green's function Spline Transmission line matrix methods Wideband
A novel procedure for the evaluation of the multilayered Green's function and the related method of moment (MoM) matrix is presented in this letter. The proposed technique yields accurate results and reduces the computation time in comparison to the conventional approach by using spline-polynomials for the frequency-domain interpolation of planar wideband devices. Illustrative examples that demonstrate the reliability and efficiency of the described procedure are reported.
