Analysis on Resonant Cavities of 231GHz EIA with Trapezoid Subwavelength Holes
A novel resonant cavity of extended interaction amplifier (EIA) is designed, combined with a double-grating structure and trapezoid subwavelength holes array structure. The resonant cavity is analyzed when operating at the TM31-2π mode in millimeter-wave band. The electric field distributions, dispersion, Q, and R/Q characteristics are simulated with the different parameter trapezoid subwavelength holes. Compared to the EIA which adopts the resonant cavity with rectangular holes, the one with trapezoid-hole resonant cavity may have a higher gain and wider bandwidth.
