US Patent:
20040240060, Dec 2, 2004
Filed:
Feb 18, 2004
Appl. No.:
10/487204
Inventors:
Roland Kersting - Albany NY, US
Aleksey Filin - Rensselaer NY, US
Matthew Stowe - Pasadena CA, US
International Classification:
G02B005/18
G02B027/42
US Classification:
359/558000
Abstract:
A device and method for differentiating an incident electromagnetic pulse. A conductive grating is provided with a sub-wavelength period, an area larger than the electromagnetic beam diameter, and a grating conductor thickness greater than the skin depth of the electromagnetic pulse. The grating conductors are oriented essentially parallel to the incident electromagnetic pulse to diffract the electromagnetic pulse. An aperture captures only the zero order diffraction of the electromagnetic pulse, which is the first time-derivative of the incident electromagnetic pulse.
