Patent abstract

Systems and methods are disclosed for emitting electromagnetic (EM) energy. A source emits EM energy that is incident on a first material. The first material transmits EM energy to a second material. The second material can have a first surface adjacent to the first material and a thickness and shape selected to stimulate surface plasmon polaritons on the first surface of the second material to resonate the EM energy transmitted from the first material such that the resonated EM energy has an EM wavelength in a narrow field of view with substantially no sidelobes.
