irfan1 said:Lets say you have both epsilon and mu (permiability and permittivity) equal to 0. Does this mean that the Maxwell equations reduces to static equations. What do you think?
irfan1 said:well, if both epsilon and mu are analytic functions of frequency and if they can both be negative (It has been shown that both can be negative at the same time), then at some frequency point shouldnt we have at least one of them equal to 0? Still the speed of light is not affected. These are just the relative epsilon and relative mu. But if you start from the Maxwell equations and put epsilon and mu equal to 0 after you derive the wave equation all the equations reduces to the static equations.
