Energy Transport Theorem (ETT)-Based Decoupling Mode Theory (DMT) for Wave-Port-Fed Transmitting-Receiving Systems

The previously established energy transport theorem (ETT)-based decoupling mode theory (DMT) for the wave-port-fed transmitting antennas is further extended to the wave-port-fed transmitting-receiving systems. This paper only considers the case of metallic transmitting-receiving system, and the obtained ETT-based DMT (ETT-DMT) will be further extended to the cases of material and metal-material composite transmitting-receiving systems in the future studies.
