TY - JOUR A1 - Vera Castejón, Pedro AU - Álvarez Melcón , Alejandro T1 - A Novel Technique for the Numerical Evaluation of the Green’s Functions Associated to Cavity Backed Antennas in Circular Waveguides Y1 - 2003 UR - http://hdl.handle.net/10317/1273 AB - In this contribution a simple and effective technique for the numerical calculation of the Green's functions in cylindrical shaped enclosures is developed. The technique is based on the numerical imposition of the boundary conditions for the fields at the cylindrical walls, using the theory of images. Numerical results for the Green's functions inside a cylindrical cavity are presented, including convergence test of the algorithm. Results show that numerical convergence is attained fast, therefore demonstrating the usefulness of the developed algorithm.
