Laser device emitting a far infrared wave beam having a mode confining for charged particles. The laser devices of this kind generally emit circular polarized wave beams in which the phase shift of the radioelectric oscillation at a point having a given azimuth with respect to the beam axis is...
a.The entire range over which some measurable property of a physical system or phenomenon can vary, such as the frequency of sound, the wavelength of electromagnetic radiation, or the mass of specific kinds of particles. b.A specific portion of such a range:the infrared spectrum. ...
Thanks to the limited attenuation of infrasonic waves travelling within atmospheric waveguides22, infrasound can propagate at long ranges when favourable propagation conditions exist. The eruptive time history can be tracked with greater temporal resolution compared to the information retrieved from satellite...
The electromagnetic spectrum is the range of frequencies, wavelengths as well as photon energies covering frequencies from below 1 Hz up to 1025 Hz. The entire range of electromagnetic spectrum consists of radio waves, microwaves, infrared radiation, visible light, ultraviole...
High-quality-factor space–time metasurface for free-space power isolation at near-infrared regime Space–time metasurfaces are promising candidates for breaking Lorentz reciprocity, which constrains light propagation in numerous practical applications. ...

We investigate the possibility of light beams that are both narrow and long range with respect to the wavelength. On the basis of spectral electromagnetic field representations, we have studied the decay of the evanescent waves, and we have obtained some bounds for the width and range of a lig...
Last year, the JF-17 Thunder aircraft shot down a slow speed target with BVR (Beyond Visual Range) and IR (Infrared) missile with pin-point accuracy at Sonmiani firing range marking a landmark occasion for the force as well as the whole nation. Pakistan successfully test-fires long-range ...
The small oscillations are a result of feedback of the temperature/humidity control system. Full size image Long-path THz time-domain spectrometer (THz-TDS) The THz-TDS system uses an infrared (1550 nm) 80 fs pulsed laser with a 100 MHz repetition rate. The laser pulse is split into the...
