Electric waves vector
WebIn electromagnetics, an evanescent field, or evanescent wave, is an oscillating electric and/or magnetic field that does not propagate as an electromagnetic wave but whose energy is spatially concentrated in the vicinity of the source (oscillating charges and currents). Even when there is a propagating electromagnetic wave produced (e.g., by a … WebThe most general equation for the spatial variation of the electric field for a plane wave is E ( r) = E 0 e − i k ∙ r where E 0 is some vector with no dependence on r. This can be written in terms of x, y, and z as E ( x, y, z) = ( E 0, x x ^ + E 0, y y ^ + E 0, z z ^) e x p [ − i ( k 0, x x + k 0, y y + k 0, z z)]
