Metamaterials, gamma-ray bursts, quantum gravity, and the search for the missing half of the maxwell equations

Summary form only given, as follows. Although microwave metamaterials may seem unrelated to gamma-ray astrophysics, it is shown that both phenomena may be expressed using left-handed extensions to Maxwell´s equations. Such extensions represent left-handed behavior in metamaterials and represent unknown dispersive processes in gamma-ray bursts. Recent quadratic gamma-ray dispersion models lead to modified Helmholtz equations, and result in left-handed extensions to Maxwell´s equations that are identical to metamaterial models.
