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
