Traveling EM waves with fixed energy density

Main Question or Discussion Point

Hi,
I'm taking an undergrad course in Electromagnetism and Optics, and in the lecture notes it reads:
"Consider the formal equation ε0D⋅E = 1 ... that must be obeyed for waves travelling in different directions as defined by the wave vector k but with a given energy density."
Could anyone help me as to where this equation comes from?
