“…The discontinuous Galerkin time domain (DGTD) method is widely used in the transient simulation of antennas and microwave devices because of its high accuracy. The DGTD method introduces numerical flux into the finite element time domain (FETD) method [1][2][3][4][5][6][7][8] and exhibits higher accuracy and modeling flexibility than conventional time-domain methods such as finite difference time-domain (FDTD) method. The numerical flux decomposes the common basis function between neighboring elements, so that the governing equation can be established in one element and avoid building and decomposing large sparse matrices.…”

An alternate boundary local time stepping (ABLTS) method is proposed for the discontinuous Galerkin time domain method for transient electromagnetic simulations to reduce the computation complexity of the local time stepping (LTS) method. The proposed method exhibites lower storage and time complexity than the conventional LF-LTS method . The stability, accuracy, and effectiveness of the ABLTS method are verified by applying it to the simulation of a resonator cavity and multi-layer microstrip antenna. The numerical results revealed that the developed method is effective for the transient electromagnetic simulation of antennas.
