A Microwave Anapole Source Based on Electric Dipole Interactions Over a Low-Index Dielectric
Muhammad Rizwan Akram, Abbas Semnani
The pursuit of non-radiating sources and radiation-less motion for accelerated charged particles has captivated physicists for generations. Non-radiating sources represent intricat…
A Low-Loss 1-4 GHz Optically-Controlled Silicon Plasma Switch
Alden Fisher, Zach Vander Missen, Abbas Semnani +1
This paper presents a low-loss optically-controlled inline RF switch suitable for L- and S-band applications. Under 1.5 W laser power, the switch exhibits a measured ON-state inser…
Plasma Switch-Based Technology for High-Speed and High-Power Impedance Tuning
Zach Vander Missen, Sergey Macheret, Abbas Semnani +1
This paper introduces a new technology for a high-speed, high-power mobile form-factor tuner utilizing gas discharge tube plasma cells as switching components. To the best of our k…
Negative refraction of a three-dimensional metallic photonic crystal
Ali Mahmoudi, Abbas Semnani, Ramazan Alizadeh +1
A metamaterial with a negative effective index of refraction is made from a three-dimensional hexagonal lattice photonic crystal with a metallic basis embedded in foam. It has been…
