Thermal-Mechanical-Electromagnetic Multiphysics Simulation of Satellite Phased Array Antenna Based on DGTD and FEM Method

An advanced multiphysics numerical methodology is introduced for simulating satellite phased array antennas, encompassing thermal, mechanical, and electromagnetic aspects. The finite element method (FEM) is employed for thermal and mechanical simulations, while the electromagnetic simulation is executed using the discontinuous Galerkin time-domain (DGTD) method. A multiphysics field coupling mechanism is devised to enable seamless co-simulation of thermal, mechanical, and electromagnetic phenomena. The capability, precision and versatility of the proposed method for multiphysics simulation of satellite phased array antennas are substantiated through comprehensive numerical examples.
