Antenna System Generating Quasi Relativistic Radiation |
摘要 |
An antenna system that generates radiation similar to that generated by a relativistic charged particle is provided. The antenna system includes a conducting wire carrying a current pulse with a net charge, called a quasi charged particle, which propagates near the speed of light and emits radiation. Preferably, the quasi charged particle is generated by using a pulsed laser to knock out electrons from the conducting wire. While propagating on the conducting wire near the speed of light, the quasi charged particle generates a synchrotron like radiation from a bent of the wire, an undulator like radiation from a sinusoidal or helical structure of the wire, a diffraction like radiation from an aperture transmitting the wire, a Smith-Purcell like radiation from a corrugated grating surface next to the wire, and a greatly wavelength-contracted undulator like radiation from an undulator with the wire aligned along the undulator axis. |

1. A radiation antenna system, comprising:
a laser excitation unit, emitting a laser pulse; a quasi charged particle generation unit, receiving the laser pulse to knock out a plurality of electrons through photoemission from a conducting wire to induce a pulsed charge wave carrying a net charge, called a quasi charged particle, and traveling on the conducting wire; and a radiation generation unit, having the conducting wire carrying the quasi charged particle therein moving with a component toward a radiation detector and generating a quasi relativistic electromagnetic radiation collected by the radiation detector. |
