... changes. Amplifying currents, on the other hand, have been argued to generate a positive feedback effect that amplifies voltage changes, and hence make existing resonances more pronounced (Hutcheon and Yarom 2000) but they do not create resonance by themselves. Prototypical examples of resonant curr ...

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.
