Tunable Fabry-Perot cavity THz antenna based on leaky-wave propagation in nematic liquid crystals
A novel terahertz (THz) Fabry–Perot cavity (FPC) antenna is proposed, based on a multistack of alternating layers of highly birefringent nematic liquid crystal (NLC) and highpermittivity dielectric, which comprehensively acts as a Bragg reflector. This layout is able to provide enhanced reconfigurability
