| 释义 | > as lemmascavity resonator b. In full cavity resonator. A waveguide which is capable of containing electromagnetic fields having particular frequencies of oscillation, and of exchanging electrical energy with them (used esp. for the amplification and detection of microwaves); a system with similar properties, such as a length of coaxial line.

IRE 24 1320 All of these terminals may act as more or less sharply resonant systems... They may..be thought of as electromagnetic analogues of the Helmholtz resonator.] 1936 Proc. IRE 24 1324 A cylindrical resonator attached to the hollow tube system. 1943 Proc. IRE 31 447/2 The flexibility of the Klystron is seriously limited by the fact that cavity resonators are permanently attached to the grids and thus form an integral part of the tube. 1950 Physical Rev. 79 696/1 A capacitatively loaded coaxial-line resonator. 1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) II. 577/2 Coaxial cavity resonators are often used as wavemeters, particularly for lower than microwave frequencies. 2000 J. McFall tr. K. Wille Physics of Particle Accelerators v. 152 Waveguides are preferred as resonators and to conduct the beam, since they have low losses and can deliver very high power. < as lemmas |
