A band-pass filter includes a photonic crystal having a local mode that generates a pass band in a stop band formed by Bragg reflection, a transmission channel that limits electromagnetic waves propagating in the photonic crystal to a mode in which an amplitude direction of an electrical field is a particular direction; and a magnetic field-applying unit for applying to the photonic crystal a DC magnetic field in a direction perpendicular to a propagation direction of the electromagnetic waves. The photonic crystal includes a periodic structure including a low permittivity dielectric member and a plurality of high permittivity dielectric members periodically arranged in the low permittivity dielectric member so that the Bragg reflection occurs in the periodic structure, and a magnetic member disposed in the periodic structure.       Recently Added Patents Plastic container with elongated vertical formation Apparatus and method for marking start and end bytes of instructions in a stream of instruction bytes in a microprocessor having an instruction set architecture in which instructions may inclu Air purifier and humidifier Pedometer Tool Wall-mounted computer work station Profile measuring apparatus, method for measuring profile, and method for manufacturing product   Randomly Featured Patents Apparatus for carrying ophthalmic lenses Toy stringed instrument Hydrogenation process of chlorinated nitrobenzene Conductive sheet Mobile communication system and control method for setting the initiation of data communication Arrow point with self lubricating collar Thermoelectric personal environment appliance Decorative self propelling spinner attached like a hubcap to the wheel of a vehicle Tamper indicator Process for producing steel by converter © 2006-2008 PatentGenius.
