Tunable triple-band millimeter-wave absorbing metasurface based on nematic liquid crystal

AIP Advances, 2022
We propose and design a tunable triple-band millimeter-wave absorbing metasurface based on nematic liquid crystal (NLC). Numerical results based on both effective circuit model and full-wave simulations verify the triple-band absorption property.

Josephson Junctions defined by a Nano-Plough

, 1998
We define superconducting constrictions by ploughing a deposited Aluminum film with a scanning probe microscope. The microscope tip is modified by electron beam deposition to form a nano-plough of diamond-like hardness, what allows the definition of ...
