介质环加载喇叭是由Toshio satoh在1972年首先研制成功的,我国杨世华等同志也用实验的方法研制成功这种喇叭。章日荣和刘顺祥等解决了介质环加载波导与光壁波导的模转换问题,导出了这种喇叭的工程设计公式。这种喇叭内有一节带着介质环的波导,从左面光壁波导入射的电磁波在此节波导内转换为介质环加载波导的混合模。这些混合模在其右边的光壁波导转换为TE模和TM模。适当选择介质环的参数和尺寸,可以使喇叭获得很好的辐射特性。 Media ring loading horn was first developed by Toshio Satoh in 1972, and Yang Shihua and other comrades in our country also successfully developed this horn by experiment. Zhang Rirong and Liu Shunxiang solved the dielectric ring loading waveguides and optical wall waveguide mode conversion problem, derived this speaker engineering design formula. In this horn, there is a waveguide with a dielectric ring inside which the electromagnetic waves incident from the waveguide on the left wall are converted into mixed modes of the dielectric ring-loading waveguide. These hybrid modes are converted to TE modes and TM modes on the right-hand optical wall waveguide. Appropriate choice of media ring parameters and dimensions, you can make speakers get good radiation characteristics.
