About this document

Diffraction Propagation Models by Juan Matias is a document available to read on EtoBox.

This document provides recommendations for calculating field strengths over diffraction paths, including accounting for a spherical earth surface or irregular terrain with different obstacle types. It describes basic concepts related to diffraction including Fresnel ellipsoids and zones, penumbra width, diffraction zones, obstacle surface smoothness, isolated obstacles, and types of terrain. Models and methods are presented to evaluate the effect of diffraction on received field strength over various path g
