✦ Synopsis
The electric fields of the spatial Green's functions of microstrip structures are calculated by numerically integrating the Sommerfeld integrals along the Sommerfeld integration paths. To facilitate and accelerate con¨ergence, a higher order asymptotic extraction is made in the integrand. The electric field components on the interface in the spatial domain are calculated directly and tabulated. They are then used in the computation of impedance matrix elements of nono¨erlap patches in the spatial domain by simple quadrature integration o¨er the spatial extent of the testing and the basis functions. Numerical results for electric surface fields of the spatial Green's functions and impedance matrix elements are illustrated for a distance range from 0.02 to 1.5 free-space wa¨elengths.
