Homework Statement
When the capacitor driven by DC voltage ##V_0##,it has the electric field distribution ##f(x,y,z)##
When ##V=V_0e^{iwt}##,how to show the EM travel in the space forever like the light?
Homework Equations
##-{\nabla}^2E-u{\epsilon}\frac{{\partial}^2{E}}{{\partial}t^2}=0 (1)##
derived from Maxwell equation.
The Attempt at a Solution
I firstly think ##E(x,y,z,t)=e^{iwt}f(x,y,z)##.But this is not right,since ##f(x,y,z)## makes electric field not travel too long.
