High-Frequency Electromagnetic Coupling Calculation Using the Dynamical Energy Analysis by Discrete Flow Method

Abstract

We introduce the Dynamical Energy Analysis (DEA) as a method to calculate high-frequency electromagnetic radiation inside a complex geometry which is not-restricted to either weak-coupling between sub-cavities or weak-damping limitation. A comparison between the results obtained using DEA and Power Balance (PWB) methods shows that, while the PWB method is sufficiently accurate in the weak-damping limit, this is not the case when damping is strong. The DEA approach may therefore be more applicable to conditions such as a fully manned cabin or other practical situations in the aerospace sector.
