Analysis of antennas on curved multilayer structures by using the GIDMULT routine

This paper describes an algorithm and FORTRAN subroutine GIDMULT for calculating the spectral domain Green's functions of coaxial cylindrical multilayer structures with any number of layers. The subroutine has been applied to analyze microstrip patch antennas on such structures and to study scattering from strip-loaded and corrugated cylinders. These examples are summarized. Different versions of GIDMULT exist for planar and cylindrical structures, and they have been extensively tested against results published by others.
