Equation (7) is the three dimensional wave equation for each component of the electric field, with a wave speed c = 1/ √ µ 0 0 = 3× m/s, the speed of light. Plane wave solutions Rather than messing around with the wave equation in general, let’s go back to Maxwell’s equations and find the plane wave solutions directly. Simple Derivation of Electromagnetic Waves from Maxwell’s Equations By Lynda Williams, Santa Rosa Junior College Physics Department Assume that the electric and magnetic fields are constrained to the y and z directions, respectfully, and that they are both functions of only x and t. This will result in a linearly polarized plane wave travelling. (source-free Maxwell’s equations) () The qualitative mechanism by which Maxwell’s equations give rise to propagating electromagnetic fields is shown in the figure below. For example, a time-varying current J on a linear antenna generates a circulating and time-varying magnetic field H, which through Faraday’s law generates a.

Plane wave solutions Rather than messing around with the wave equation in general, let’s go back to Maxwell’s equations and find the plane wave solutions directly. Chapter 1 Introduction Maxwell’s Equations Electromagnetic wave propagation is described by particular equations relating five vector fields E, D, H, B, J and the scalar field ρ, where E and D denote the electric field. Simple Derivation of Electromagnetic Waves from Maxwell’s Equations By Lynda Williams, Santa Rosa Junior College Physics Department Assume that the electric and magnetic fields are constrained to the y and z directions, respectfully, and that they are both functions of only x and t.

For example, a time-varying current J on a linear antenna generates a circulating and time-varying magnetic field H, which through Faraday’s law generates a. The wave equation is an example of a linear differential equation, which means that if ψ1(,x t)and ψ2 (,x t) are solutions to the wave equation, then ψ1(,x t)±ψ2(x,t)is also a solution. The implication is that electromagnetic waves obey the superposition principle. -Introduction to Maxwell’s Equations • Sources of electromagnetic fields • Differential form of Maxwell’s equation • Stokes’ and Gauss’ law to derive integral form of Maxwell’s equation • Some clarifications on all four equations • Time-varying fields wave equation • Example: Plane wave - Phase and Group Velocity.
