    Graduate What does this boundary condition mean?

    Hello! I have a question related to this. This boundary condition yield from n.B = 0 , but i don't know how, from considering a cylindrical waveguide. I know that there is an equation (first of 8.24 from Jackson) but i don't realice how to use it. If u know, please let me know. Thankss

    Why Are Good Conductors Opaque to Visible Light Based on Skin Depth?

    Hello! I am studying the same thing! Well, let me do an atempt here... Firstly, remember that in conductors, the wave number is complex, so k = Re(k) + i Im(k) The expression for k^2 can be derived from maxwell equations. Then you have to take the sqrt of the compley number. You found...

    Graduate Spreading of a pulse as it propagates in a dispersive medium

    Hello everyone! I am studying the spreading of a pulse as it propagates in a dispersive medium, from a well known book. My problem arise when i have to solve an expression. Firstly i begin considering that a 1-dim pulse can be written as: u(x,t) = 1/2*1/√2∏* ∫A(k)*exp(ikx-iw(k)t) dk...
