An experimental demonstration of transparency in the epsilon‐negative (ENG) and mu‐negative (MNG) pair using the composite right/left‐handed transmission line (CRLH‐TL) is presented. An eight‐cell 1D microstrip transmission‐line structure consisting of a ladder network of four CRLH unit cells with MNG characteristics connected to a ladder network of four CRLH unit cells with ENG characteristics is fabricated and tested. The transparency resulting from the cascading of MNG unit cells with ENG unit cells is observed in the S ‐parameter measurements and a circuit simulation of the voltage distribution. © 2005 Wiley Periodicals, Inc.
