介質(zhì)環(huán)加載喇叭的理論分析
THEORETICAL ANALYSIS OF THE DIELECTRIC LOADED HORN
-
摘要: 本文對介質(zhì)環(huán)加載邊界條件特征方程進(jìn)行了求解。導(dǎo)出了介質(zhì)環(huán)加載波導(dǎo)與光壁波導(dǎo)連接處的模轉(zhuǎn)換計算公式。并且根據(jù)這些公式計算了文獻(xiàn)[1]設(shè)計的介質(zhì)環(huán)加載喇叭的輻射特性,計算結(jié)果非常接近實(shí)測結(jié)果。

Abstract: This paper gives a solution of the characteristic equations of the boundary conditions of the dielectric ring loaded horn. This leads to transformation formulas for the connecting boundary of the dielectric ring loaded waveguide and smooth walled waveguide. Using these formulas, the radiation characteristics of the dielectric ring loaded horn according to the design in reference [1] are found. The calculated values are very close to experimental results. -
