Design of Corrugated Circular Horns

This work is a summary of a research work. The author explains how is it possible design corrugated circular horns in a easy way using few formulas and concepts. These formulas are sufficient unless the design constraints of the project are very strict, such as radio astronomy applications. In this latter case optimization of the parameters is necessary using some kind of algorithm or mathematical method. An example of application for ALMA (Atacama Large Millimeter Array), Chile, is showed.
