Thank you for your response Creator. Believe my confusion was considering E and B as sharing the energy of the wave (similar to K.E. and potential sharing the total E). Will dig out my undergraduate intermediate EM book and review more throughly (still confused as to where the energy is stored...

Have viewed PF, first time post (have searched for this question on forum): The energy of EM radiation can be described by the Poynting vector S = E x B (insert conversion factor for cgs, MKS, etc). For a traveling EM wave, what happens to the instantaneous value of S when E and B are...
