这是使用射线跟踪法求解墙体造成误差的程序，分别有穿单面墙，平行双墙，垂直双墙的情况-This is to use ray-tracing procedure for solving the error caused by the wall, respectively, through a single wall, parallel to the double wall, vertical double-wall case

Matlab source code for calculation dispersion properties of tubular double-wall dielectric waveguides. FEMlab codes for calculations distributions of magnetic and electric fields in it.
