I. Sirkova et He. Hernandez-figueroa, Local transparent boundary condition applied to the modeling of tropospheric ducting propagation, MICROW OPT, 21(5), 1999, pp. 343-346
An efficient numerical scheme to simulate tropospheric ducting propagation
(TDP) is presented in this paper. This scheme solves the parabolic equation
(PE) approximation in conjunction with the finite-element method (FEM) and
the local transparent boundary condition (LTBC) It is shown that a simple
LTBC can be effectively used to account for the radiation in TDP, instead o
f the recently published nonlocal transparent boundary condition (NTBC), wh
ich is much more complex and consumes more computer time. (C) 1999 John Wil
