Measurement of the THz emission from a femtosecond laser filament
... where pe is the plasma electronic frequency in Hz, e is the electron collision frequency and τL= 50 fs is the laser pulse duration. We fit the measurements by convoluting the filters transmission to the distribution g(pe, e). pe determines the maximum of the distribution and e its width. Since ...

RADAR CROSS-SECTION STUDIES OF SPHERICAL LENS
... attached metallic spherical cap [2–6]. In this paper we consider the possibility of replacing the relatively-expensive-to-manufacture LL by the cheaper SL. The use of SLs for antenna design has been intensively discussed in the 50’s and 60’s (see, for example [7, 8]). Nowadays, this idea appears to ...

health monitoring of induction motor for vibration analysis
... The frequency of the vibrations can also be mapped since certain frequencies will only be present when conditions that indicate an impending defect are present. Comparison of the vibration spectra of new equipment versus equipment that has been used will provide the information required to make a de ...

Longitudinal Output Voltage Limitations
... under test. Comparison of VDSL2 PSD and TB Limits with VDSL2 LOV Limits Assuming that the TE is well balanced to ground and does not generate longitudinal signals, it should have no problem meeting the LOV limits. A comparison of the VDSL2 LOV limits to the VDSL2 PSD mask limits and applicable Trans ...

Since the voltage has reached its maximum value, the system works with maximum efficiency though it does not deliver the maximum power. The quarter wavelength line, enable the carrier (main) am ...

Electromagnetic Radiation (EMR) and Remote Sensing
... Nonselective scattering has impacts on almost all spectral bands. In visible wavelengths, water droplets and ice crystals scatter all wavelengths equally well so that the clouds in the sunlit sky looks white. Also large smog particles cause the color of sky to grey. ...

Digital electronic drivers type E-MI-AS-IR
... reduces static friction effects. Dither frequency can be set in a range from 80 to 500 Hz (default value is 200Hz). Lower dither setting reduces the hysteresis but also reduces the regulation stability. In some application this can lead to vibration and noise: right setting usually depends on system ...
