Homework Statement
find all elements of maxwell stress tensor for a monochromatic plane wave traveling in z direction and linearly polarized in x.
Homework Equations
Tij=[tex]\epsilon[/tex]o(EiEj-(1/2)[tex]\delta[/tex]ij E2+1/[tex]\mu[/tex]o(BiBj-(1/2)[tex]\delta[/tex]B2
The Attempt at a Solution
So i found what E and B is well not really important to my question but E =Eocos(KZ-wt) X direction
B=1/c Eocos(KZ-wt)Y direction
I have the solution, but kind of confused. They only found Txx Tyy Tzz why didnt they find Txy ext or is that wht it means by find all elements, just xx yy zz
So i found wht Txx is and I got TXX=1/2([tex]\epsilon[/tex]oE2-B21/[tex]\mu[/tex]o they got the same but than that = to zero. Why does it TXX= to zero? Same for Tyy
thanks
