Sentence examples for frequency range of absorption from inspiring English sources

Line broadening, in spectroscopy, the spreading across a greater wavelength, or frequency range, of absorption lines (dark) or emission lines (bright) in the radiation received from some object.

Moreover, the introduction of tubes in a cavity of a conventional resonator generates a significant shift in the frequency range of absorption towards lower frequencies or allows a reduction of cavity thickness.

From the analysis and design examples, we confirmed that the perforated plate using multiple-sized holes and a porous separating partition can make a continuous frequency range of high absorption coefficient compared to the perforated plate with a conventional rigid partition.

The frequency ranges of infrared absorption are consistent on the whole, but the N-oxides still affect some characteristic absorption bands shifting.

As the light is tuned across the frequency range of interest and the absorption or fluorescence is recorded, extremely narrow spectral features can be measured.

The effects of the parameters are examined, and a practical method of broadening the frequency range of the effective sound absorption is discussed.

Exploring effective microwave absorption materials is always a challenge especially in the relatively low frequency range of 2 8 GHz and broad absorption band.

The double-layer FCI/CF composites show a wider absorption frequency range of 12.0 GHz from 6 to 18 GHz with reflection loss (RL) below −5 dB at thickness of 0.8 mm.

Therefore, in this manuscript, we only discuss the resonance peaks (i.e., the modes A, B, C, and D) with high absorption coefficients of the frequency range of (0.2~3) THz without considering the cases of the low absorption coefficients and the unpredictable frequencies of the modes in the frequency ranges of (3~6) THz and (3~8) THz.

Absorption bands in the frequency range of 1610 1625 cm−1 are expected to represent β-sheet structure [22], [23], whereas absorption bands in the frequency range of 1640 1650 cm−1 are ascribed to the overlapping peaks at 1652 cm−1644644 cm−1, and 1632 cm−1 of the coiled-coil fingerprint spectrum [24].

We fabricated THz-wave detectons on LiNbO3 substrates that have a high absorption coefficient for the frequency range of 1012 Hz.
