APPLICATIONS OF ONE‐DIMENSIONAL GREEN'S FUNCTION APPROACH FOR THE ANALYSIS OF SINGLE AND COUPLED SET OF EM SOURCE EXCITED TRANSMISSION LINES

The excitation is assumed to be due to voltage and sources placed anywhere on the lines. These lines are generally assumed to be uniform along the direction of wave transmission; however, for a certain class of lines, as for example those supporting only a transverse electromagnetic (TEM) or quasi TEM mode, the analysis can be extended to allow for the electrical parameters to vary along the length of the line, as will be indicated. At microwave and millimeter waves, circuits are often tightly packed to achieve miniaturization; in such cases, electromagnetic interference (EMI) issues arise due to electromagnetic (EM) coupling between the circuits. The chapter deals with a multiconductor set of transmission lines that exhibit such EM coupling effects. An analysis of multiconductor lines is developed via a matrix Green's function method to solve a coupled set of one‐dimensional Sturm‐Liouville problems pertaining to the case.
