Using them could be easier if we decouple the equations. We see therefore that the electric and magnetic fields satisfy an equation for waves that propagate at the speed c 1 µ 0ǫ 0 299792 108 metressecond. We deal with both normal and non-normal angles of incidence.
E electric eld is always perpendicular to the direction the electromagnetic wave is traveling and is always perpendicular to the magnetic eld. Wave Solutions to Maxwells Equations. E electric and magnetic elds are in phase.
We can expand our wave equation in Cartesian coordinates. Maxwells Equations for Electromagnetic Waves 61 Vector Operations Any physical or mathematical quantity whose amplitude may be decomposed into directional components often is represented conveniently as a vector. The Wave Equation for E and B In vacuum each Cartesian component of E and B satisfies the three-dimensional wave equation 2 2 00 2 2 2 2 22 2 00 2 1 t f f vt t µε µε E E B B Maxwells equations imply that empty space supports the propagation of electromagnetic waves traveling at a speed 8 00 1.
Similarly t is the time at which the fields are evaluated. 5-02-2007 Preparatory School on Fiber Optics Fiber Lasers and Sensors 2 Maxwells Equations. 8 00 1 c x m s 2997 10 PH.
When the values forµ0 andε0 are entered into the equation forc we find that c 1 242. In the absence of free charge and current densities the Maxwell equations are. 134 Plane Electromagnetic Waves To examine the properties of the electromagnetic waves lets consider for simplicity an electromagnetic wave propagating in the x-direction with the electric field E G pointing in the y-direction and the magnetic field B G.
