主 题:Hilbert transform march-on-in-time time-accelerated integral equation.
摘 要:Based on the Hilbert transform, this paper presents a totally new method to obtain the time-accelerated electric field, magnetic field and combined field integral equations for the two-dimensional transient scattering problems. The computational complexity of the time-accelerated integral equations is analysed, which can be reduced to O(N_s^2NtlogNt) from the conventional O(N_s^2N_t^2). Numerical results verify the computational complexity of this time-accelerated method, and show that the time-accelerated integral equations can provide accurate and stable solutions for both the open and closed objects.
