摘要：
The first theoretical study of thermal time, constants in MMIC grid arrays is presented, indicating the significance of time dependent thermal effects for spatial power combining. Model validation against thermal images of passive grid arrays provides the first experimental demonstration of the impact of natural convection on grid array beam forming.
