## Photon density of states for inverse diamond

The dispersion relation for inverse diamond was calculated using the plane wave method.

$\frac{a\omega}{2\pi c}$ | |

The numerically calculated density of states is,

$\frac{D}{\text{unit cell}}$ | |

| $\frac{a\omega}{2\pi c}$ |

A description of the calculation can be found here. The associated matlab files.
