IEEE Antennas and Wireless Propagation Letters. 13:427-430
In this letter, we present a nonlinear metamaterial capable of transitioning between a broadband reflective and broadband nonreflective state depending on the incident power level. Below the activation voltage, broadband reflectivity is created by fo

There are often discrepancies between the behavior of a metamaterial reflector unit cell in an infinitely periodic environment and in a non-ideal environment in which the reflection phase varies across a metamaterial reflector. This work considers th

We propose a metasurface with reconfigurable reflection phase that can be utilized in high power microwave (HPM) applications. The structure relies on capacitor networks controlled by appropriately biased PIN diodes. Simulations reveal that the metas
