Modal Transmission-Line Modeling for Electromagnetic Wave through Building Structures

The modal transmission-line (MTL) method is applied to analyze the transmission and reflection effectiveness of building structures. The paper improves a previous study of MTL method and extends the method to transverse magnetic (TM) polarized mode of obliquely incident plane radio wave based on a more general building structure model in 2-D settings. Simulation results are compared, and the enhanced MTL method is proven effective.
