A metamaterial lens consisting of a paraboloid of revolution that separates two portions of space having real and opposite refractive indexes but the same intrinsic impedance is considered, as well as a lens consisting of a paraboloidal double‐negative radome. For both lenses, geometrical optics yields the exact electromagnetic field for an axially incident plane wave.
