    Graduate On Skin Effect and Microstrip Lines

    Oh my, I think I have pinned down the source of my doubt. It all happened when I first learned about skin depth, where there was an equation of electric field in a good conductor E_x = E_0 * e^{-\alpha * z} * cos(\omega * t - \beta * z) \alpha = \sqrt{\omega \mu \sigma} I mistakenly thought...

    If conductor is ideal, there is no $E_{parallel}$, thus there is no resistive conductor loss (or the so called skin effect)

    Graduate On Skin Effect and Microstrip Lines

    I was talking about a Poynting vector that is perpendicular the the conductor. It has been well answered by Bob. The only doubt left is, given the conductors are ideal, will an AC current be on the surface, instead of distributed evenly? If so, then we have two separate phenomena both of which...

    Graduate On Skin Effect and Microstrip Lines

    Well this is refreshing. So in reality there is a vertical component close to the conducting medium? Is there any source that elaborates on this?

    Graduate On Skin Effect and Microstrip Lines

    In the field of microwave engineering, skin effect is referred to when people talk about the fact that current, that is, electrons only flows on the surface of transmission lines, e.g. microstrip lines. I've checked many EM books--everywhere skin effect is demonstrated with both E and H...
