英文摘要：

The parallel higher-order method of moments is firstly utilized to simulate electromagnetic radiation and scattering problems on a domestically-made supercomputing platform with its parallel efficiency tested. Higher-order polynomials over wires and quadrilateral plates, which can ensure accuracy, are used as basic functions over larger subdomain patches to reduce the number of unknowns. The parallel strategies based on block matrices can improve the computational scale and simulation speed. Numerical results show that the self-developed procedures provide an effective way to solve complex electromagnetic problems on the supercomputing platform.
