Abstract
GRASP[1], the well-known program for antenna simulation, includes hybrid modes of circular corrugated waveguide as a field source. But only balanced modes are computed, being those of widest interest for antennas. Studying radiation of hybrid modes in very broadband applications (e.g. reflectometry in fusion experiments) often requires to cope with unbalanced conditions at band extrema. A FORTRAN90 program was written for writing the field of a chosen hybrid mode on the aperture of a circular corrugated waveguide in a format compatible with tabulated sources in GRASP[3]. The formulation was taken from [2]. The program is available in the public domain as a .tar.gz archive at the same location as this report.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
