Hi guys. I want to know if anybody can tell me a program which helps to do draws and diagrams. I want to do figures like those what appear in electromagnetic and waves book. For example, draw an arrow and label the angle with a line as "alpha" or thinngs like it. Thank you.

And I can use electric and optic multiplex, too.

I have to find the maximun bps that it can be reach using a point-to-point link of 40 km long of optic fiber. I use an ITU normalized channel (100 GHz optic BW). So, I can choose any electric modulation and any optic modulation, too. Anybody could help me? Any answer is welcome. Thanks.

Thanks a lot for your reply. I will check the book as fast as I can. Other replies will be welcomed, too.

I wish somebody could tell me if he knows articles or information about modeling circular apertures in a transverse metalic plate in a rectangular waveguide. It appears in the "Waveguide Handbook" by N. Marcuvitz, on page 238. Can anybody help me to find more information about this theme? Thanks...
