“…The spectral response of the n-Ge antennas in the THz range can be reliably simulated by solving Maxwell's equations using a Finite Element Method (FEM), with input data such as geometry, density, arrangement and stack materials [10,13]. Comprehensive FEM simulations have been made, using the method and parameters as described in [10].…”

Localized Surface Plasmon Resonances (LSPR) based on highly doped semiconductors microstructures, such as antennas, can be engineered to exhibit resonant features at THz frequencies. In this work, we demonstrate plasmonic antennas with increased quality factor LSPRs from Fano coupling to dark modes. We also discuss the advances in the biofunctionalization of n-doped Ge antennas for specific protein immobilization and cell interfacing. Finally, albumin biolayers with a thickness of a few hundred nanometers are used to demonstrate the performance of the fano-coupled n-Ge antennas as sensors. A resonant change of over 10% in transmission, due to the presence of the biolayer, can be detected within a bandwidth of only 20 GHz.
