The Resonance Condition for Slow Wave Antennas: a Lagrangian Approach

Autor: Nevels, Robert, Scully, Steven, Espinal, Francisco, Svidzinsky, Anatoly

A proof of the resonant property of linear periodically loaded antennas with subwavelength elements is obtained by applying a Lagrangian formalism. A Lagrangian is developed by modeling the antenna with lumped inductance and capacitance elements on a

UNBLOCK: Low Complexity Transient Blockage Recovery for Mobile mm-Wave Devices

Autor: Ganji, Santosh, Lin, Tzu-Hsiang, Espinal, Francisco A., Kumar, P. R.

Directional radio beams are used in the mm-Wave band to combat the high path loss. The mm-Wave band also suffers from high penetration losses from drywall, wood, glass, concrete, etc., and also the human body. Hence, as a mobile user moves, the Line
