Abstract:Employing the work-energy principle based physical interpretation for characteristic mode theories (CMTs), it is exposed that: strictly speaking, the existing CMTs are the modal analysis theories for incident-field-driven scattering objects and lumped-port-driven transmitting antennas, but not for wave-port-fed transmitting antennas, so they cannot provide an exact modal analysis to wave-port-fed antennas. This paper focuses on establishing an effective modal analysis theory for wave-port-fed antennas. Power t… Show more
