Abstract:
An assembly for receiving and transmitting millimeter (mm) waves, including at least one mm wave reflector (84, 86, 88)and at least one mm transmission wave feed (72) configured in a transmission feed location (34) within the at least one mm wave reflector. The assembly also includes a plurality of receiving mm wave feeds (72) configured in respective receiving feed locations (36) within the at least one mm wave reflector; and a radio frequency (RF) module (38). The RF module is coupled to the at least one mm transmission wave feed and to the plurality of the receiving mm wave feeds, so as to drive the at least one mm transmission wave feed to transmit outgoing mm waves and to simultaneously receive incoming mm waves from all of the plurality of the receiving mm wave feeds.
Abstract:
In general, in one aspect, the invention features methods that include guiding radiation at a first wavelength, ?1, through a core of a photonic crystal fiber and guiding radiation at a second wavelength, ?2, through the photonic crystal fiber, wherein |? 1 - ? 2| > 100 nm.
Abstract:
In general, in one aspect, the invention features systems, including a photonic crystal fiber including a core extending along a waveguide axis and a dielectric confinement region surrounding the core, the dielectric confinement region being configured to guide radiation along the waveguide axis from an input end to an output end of the photonic crystal fiber. The systems also includes a handpiece attached to the photonic crystal fiber, wherein the handpiece allows an operator to control the orientation of the output end to direct the radiation to a target location of a patient.
