A Reflective Metasurface for High-Efficiency Terahertz Cross-Polarization Conversion
Muhammad Fayyaz Kashif, Shobit Agarwal, Antonio Iodice +5
We demonstrate a reflective terahertz (THz) polarization conversion metasurface based on a double-ring aluminum resonator on a quartz substrate. Full-wave simulations are used to o…
Sensing enhancement of a Fabry-Perot THz cavity using switchable VO2 mirrors
Gian Paolo Papari, Anna Lucia Pellegrino, Graziella Malandrino +1
We experimentally investigate the sensing properties of an open cavity operating in the THz regime and realized by employing as mirrors two thin vanadium dioxide (VO2) films grown…
Isotropic properties of the photonic band gap in quasicrystals with low-index contrast
Priya Rose, E. Di Gennaro, G. Abbate +1
We report on the formation and development of the photonic band gap in two-dimensional 8-, 10- and 12-fold symmetry quasicrystalline lattices of low index contrast. Finite size str…
Experimental evidence of cut-wire-induced enhanced transmission of transverse-electric fields through sub-wavelength slits in a thin metallic screen
Emiliano Di Gennaro, Ilaria Gallina, Antonello Andreone +2
Recent numerical studies have demonstrated the possibility of achieving substantial enhancements in the transmission of transverse-electric-polarized electromagnetic fields through…
Paired cut-wire arrays for enhanced transmission of transverse-electric fields through sub-wavelength slits in a thin metallic screen
Ilaria Gallina, Giuseppe Castaldi, Vincenzo Galdi +2
It has recently been shown that the transmission of electromagnetic fields through sub-wavelength slits (parallel to the electric field direction) in a thin metallic screen can be…
Bandgap properties of low index contrast aperiodically ordered photonic quasicrystals
Gianluigi Zito, T. Priya Rose, Emiliano Di Gennaro +3
We numerically analyze, using Finite Difference Time Domain simulations, the bandgap properties of photonic quasicrystals with a low index contrast. We compared 8-, 10- and 12-fold…
