Frequency and impedance reconfigurable antennas for terahertz photomixers
We present, for the first time, the design of two antennas for the terahertz photomixers that have reconfigurable operation frequency or reconfigurable input impedance as an alternative to the state-of-the-art high-impedance, narrow band or low-impedance, wide-band antennas.

This paper proposes a reconfigurable microstrip patch antenna design for wireless ISM band applications. The antenna simultaneously uses PIN Diodes to switch between linear and circular polarization at 2.45 GHz and uses Varactor Diode to continuously tune the operating frequency from 1.73 GHz to 2.45 GHz.

Design of a frequency reconfigurable, terahertz antenna for photomixers
We present the fabrication-ready design of a frequency reconfigurable terahertz antenna for photomixers using Nano-Electro-Mechanical Systems (NEMS) switches. The proposed antenna is a dipole antenna, where the physical length of the antenna is changed using NEMS switches, which enables high radiation resistance at two different frequencies, namely 320

"Reconfigurable Plasma Frequency Selective Surface "
This paper presents single- and double-layer reconfigurable frequency selective surfaces (FSS) for high-power microwave (HPM) shielding, utilizing plasma as an active element. Unlike conventional FSS, plasma-based design enables tunable filtering by adjusting plasma density or shape, reducing the need for extensive structural modifications.
