Introduction to electromagnetic plane waves
Electromagnetic plane waves are fundamental to understanding the behavior of electromagnetic radiation in various contexts, ranging from communication systems to optical technologies. These waves, which are solutions to Maxwell’s equations, represent a uniform and periodic disturbance in the electric and magnetic fields that propagate through space. An electromagnetic wave is composed of oscillating electric and
