Modeling of Pyramidal Absorbers for an Anechoic Chamber

Application ID: 12129

In this model, a microwave absorber is constructed from an infinite 2D array of pyramidal lossy structures. Pyramidal absorbers with radiation-absorbent material (RAM) are commonly used in anechoic chambers for electromagnetic wave measurements. Microwave absorption is modeled using a lossy material to imitate the electromagnetic properties of conductive carbon-loaded foam.

This model example illustrates applications of this type that would nominally be built using the following products:
