[[Plane wave]]s are solutions to the homogeneous [[Helmholtz equation]], and form a basis to represent fields in the periodic media. PWE as applied to photonic crystals as described is primarily sourced

from Dr. Danner's tutorial.<ref>http://www.ece.nus.edu.sg/stfpage/eleadj/planewave.htm</ref>.

The electric or magnetic fields are expanded for each field component in terms of the [[fourier series]] components along the reciprocal lattice vector. Similarly, the dielectric permittivity (which is periodic along reciprocal lattice vector for photonic crystals) is also expanded through Fourier series components.
