Difference frequency generation of infrared waves in asymmetric quantum wells.There has been a great deal of interest in recent years in the investigation of signals in the terahertz frequency range of the electromagnetic spectrum. One impediment to this ongoing research is the lack of useful sources...

Thus, in the case of a two-sublattice structure, there should be a single oscillator response to a transverse electromagnetic field. The resonance frequency ωT is typically in the infrared range. Other phonon modes will usually also exist, but here we are only concerned with the infrared-...

n.an electromagnetic wave frequency between audio and infrared radio frequency_航天行业词汇 射频 radio frequency_铁道行业词汇 射频 radio frequency医学词典英英释义 radio frequencynoun any of the electromagnetic wave frequencies that lie in a range extending from below 3 kilohertz to about 300 gigahertz ...
Radio waves are electromagnetic waves whose wavelength is more than the infrared rays. Therefore, the frequency of the radio waves is less than that of the infra-red rays. Wave Travel: The wavelength of a wave, {eq}\lambda {/eq} (m), is the distance...
