In this work we analyze the tunable properties of a Fabry-Perot cavity leaky-wave antenna based on nematic liquid crystals (NLCs). The possibility of dynamically tuning the permittivity of an NLC layer through the application of a low driving voltage is exploited in order to affect the propagation constant of the TM fundamental leaky mode supported by the planar structure. A suitable configuration is analyzed in the low-THz range. Numerical results confirm the reconfigurability of the proposed devices, making them potentially very attractive for THz applications.

Abstract
In this work we analyze the tunable properties of a Fabry-Perot cavity leaky-wave antenna based on nematic liquid crystals (NLCs). The possibility of dynamically tuning the permittivity of an NLC layer through the application of a low driving voltage is exploited in order to affect the propagation constant of the TM fundamental leaky mode supported by the planar structure. A suitable configuration is analyzed in the low-THz range. Numerical results confirm the reconfigurability of the proposed devices, making them potentially very attractive for THz applications.File in questo prodotto:
