Abstract
In this letter, the concept of electromagnetic time reversal is applied to compensate for the non-linear phase response of a dispersive transmission line. To achieve a significant phase distortion on a short transmission line, a special type of transmission lines is chosen as an experimental platform. This special type is the so called composite right-left handed (CRLH) transmission line. The time domain response of the CRLH transmission line is calculated from a wideband frequency domain measurement.
