Calculation of Transmission and Surface-Wave Data for Plane Multilayers and Inhomogeneous Plane Layers

摘要

Digital computer programs are given for the transmission and reflection coefficients of low-loss, multilayer, radome sandwiches. Using matrix multiplication, these programs yields design data for parallel and perpendicular polarization in the most efficient manner. Typical data are included for a five-layer sandwich for normal and oblique incidence at frequencies from zero to 40 gigacycles. Matrix multiplication is also employed to calculate the phase velocity of the surface waves which may propagate on a plane multilayer sandwich. Typical results are given for three-layer and five-layer sandwiches. The transmission coefficient of an inhomogeneous plane layer is determined with step-by-step numerical integration of the wave equation. A computer program is included for this problem, along with typical computed data for an exponentially inhomogeneous layer. (Author)
