摘要：

This letter summarizes the electromagnetic field theory of stratified media and provides an approach for designing antireflection structures. The theory of stratified media has been well known for over half a century. Nevertheless, the calculation of reflection degradation is often done using the assumption of load matching. This assumption turns out to be not accurate enough for efficient design of antireflection media for radomes in the millimeter-wave regime. We introduce an approach for optimized matching in this case and show a tolerance analysis of an example structure (rib profile).
