Abstract :
Diffraction models are developed for high-frequency radiation losses calculation in rectangular iris-loaded structures. Single-cell and multi-cell models extending Lawson (1990) and Sessler-Vainshtein (1966) approaches are applied for circular, infinitely wide planar and ´muffin-tin´ geometry. For 2.5D muffin-tin structure a special semi-analytical frequency domain model is built to compare the loss calculations between diffraction model and matched field technique
