摘要
A novel MATLAB (TM)-based split-step parabolic-equation (SSPE) propagation package is introduced for the prediction of electromagnetic surface-wave attenuation along multiple mixed irregular and lossy paths. The impedance boundary condition is implemented via the discrete mixed Fourier transform (DMFT). Irregular terrain modeling is handled via coordinate transformation. Tests are performed along sea paths including smooth and hilly islands. Comparisons with ITU Recommendations and a Finite-Element-Method (FEM) based numerical propagator are given.
