Abstrak

In this letter, we propose a novel transparent boundary condition (TBC) for finite element method-based parabolic equation (PE) analysis. Conventional PE analysis uses a Hamming window, etc., adding an extra region to suppress non-physical reflected waves, which results in an increase in the amount of computation required. In this letter, a new TBC based on the matrix pencil method is proposed to suppress non-physical reflected waves. The proposed algorithm not only reduces the computational load, since it only needs to calculate up to the actual region of interest, but also shows that non-physical reflected waves at the boundary can also be effectively suppressed.
