complex numbers and differential equations
... These notes introduce complex numbers and their use in solving differential equations. Using them, trigonometric functions can often be omitted from the methods even when they arise in a given problem or its solution. Still, the solution of a differential equation is always presented in a form in wh ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
