  • Electret states in some Electrooptical Materials
    'Informa UK Limited', 2003
    Co-Authors: Cabuk S., Mamedov A.m.
    Abstract:

    In seeking an explanation of the mechanism for recording multivariate optical signal in PROM type systems (where the active layer is a sensitive Electrooptical Material) we have been studying conditions of the creation and destruction of the electret states in some ferroelectrics (LiNbO 3 and Ba 2 NaNb 5 O 15 ) with barrier and insulating contacts. The field, temperature, concentration and time dependence of the electret states and the main characteristics of traps responsible for electret states were determined. The results have been explained on the assumption that either with a decrease in temperature, the traps are partly converted into recombination centers, or the traps have a barrier and their occupation is a function of temperature

  • Active Terahertz Spoof Surface Plasmon Polariton Switch Comprising the Perfect Conductor MetaMaterial
    2016
    Co-Authors: Kyungjun Song, Pinaki Mazumder
    Abstract:

    Abstract—The feasibility of realizing an active terahertz (THz) switch by utilizing artificially corrugated perfect conductor meta-Materials is reported in this paper by demonstrating that the strongly localized THz spoof surface plasmon polariton (SSPP) modes can be easily controlled by changing the refractive index of dielectrics inside a longitudinal metallic structure with a periodic array of grooves. Specifically, this paper shows that incorporation of Electrooptical Material such as a nematic liquid crystal into the plasmonic gap leads to a highly compact and efficient THz switch that is activated by a low-voltage control-signal. The optimal design of the SSPP switch enabled by this novel method shows: 1) a strong subwavelength SSPP localization; 2) relatively high extinction ratio; and 3) small damping attenuation. Furthermore, the design flexibility associated with simple micrometer-scale ar-chitecture provides a promising method toward controlling or steering the subwavelength THz signal in the future SSPP-based compact digital circuit. Index Terms—Active circuit, bandwidth, nematic liquid crystal (N-LC), spoof surface plasmon polariton (SSPP), terahertz (THz). I
