- W4382203902 abstract "A high frequency field strength enhancement structure based on photonic crystal has been proposed. The band gap and the transmission characteristics of two-dimensional photonic crystal composed of periodic dielectric cylinder square lattice of alumina dielectric column in vacuum background are simulated by using COMSOL. The waveguide transmission and field strength enhancement are realized by designing line defect structure and resonant cavity structure. It is found that the electric field of the resonator structure can be enhanced by 10 <sup xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>4</sup> , when the input frequency is 6.48 THz. For the resonant cavity structure of photonic crystal based on dielectric cylinder, when the resonant frequency is 6.41 THz, <tex xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>$mathrm{S}11=_{-}22.09text{dB}$</tex> , and the quality factor is 687. The feasibility of input signal transmission of high frequency vacuum nano channel devices and resonant amplification of cold cathode surface excitation field has been verified. It provides a new way to improve the emission performance of vacuum field emission devices in the future." @default.
