Hi all. I'm a new member of the forum. I'm have a problem about TMz and TEz polarization. I don't understand clearly about this. So can you explain for me or give me some documents about this. Thanks very much.

Check W.C. Chu's book, one of the early chapters describes it mathematically.

http://www.amazon.com/Waves-Fields-Inhomogenous-Media-Weng/dp/0780347498/

Basically, if i recall correctly, the non-transverse (to the direction of wave propagation -- assume it's the z-direction) component of one field defines the transverse components of the other field via each of Maxwell's curl equations.

That is, for TM, the Ez field is non-transverse, and that defines the two transverse components of H. For TE, the Hz field is non-transverse, and that defines the two transverse components of E. Now if you count up what I just said, you have two non-transverse components, and four transverse components derived from those... That's all there is: 3 components of E and 3 of H. So the two non-transverse components are all you need to know to completely define the fields. Furthermore, the relationship between the two non-transverse field components Ez and Hz can often be determined via boundary conditions of the problem at hand. Thus, all the fields are defined within a scalar constant, and the field distribution of the entire problem is thus considered solved.
