 # Active CRLH Transmission Line Modeler
 
 A MATLAB simulation of an **active Composite Right/Left-Handed (CRLH) transmission line** with a frequency-dependent negative resistance element. The structure achieves controlled gain across a user-defined passband by embedding an active shunt element (modeled as a negative resistance `Rn`) within a periodic CRLH unit cell topology.
