Abstract
Printed launchers are currently used to feed millimeter broad-band horn antennas. A time-domain procedure, based on the finite-difference time-domain method, is proposed to achieve an accurate model of the launching section. A scattering matrix approach is followed and unidirectional time-domain modal sources are developed for efficient generation of port modes.
