CRLH Parameter Extraction ========================= * Setup a composite-right/left-handed (CRLH) unit cell and extract the equivalent circuit parameter. Introduction ------------- **This tutorial covers:** * Setup a feeding mircostrip line & port * Apply an inhomogeneous mesh used for improved accuracy and simulation speed * Use an internal clss to setup a CRLH unit cell * Use the port voltages and currents to extract the unit cell equivalent circuit parameter .. figure:: images/CRLH_cell.png :width: 80% :alt: CRLH unit cell with feeding MSL.
