NONRADIATING SOURCES IN TIME-DOMAIN TRANSMISSION-LINE THEORY

The concept of nonradiating (NR) sources is introduced to transmission lines in the time-domain analysis. A method is presented to construct localized voltage and current sources which do not produce any fields outside the source domain. These sources cannot, therefore, be detect ed by measurements made outside the source region. The importance of s uch sources for the uniqueness of the inverse-source problem is pointe d out, and energy conditions for the uniqueness are discussed. The ana lysis can be advantageously used in the design and optimization of the electromagnetic compatibility (EMC) properties of transmission lines.
