In a Fourier transform infrared (FT-IR) spectrometer, there is no monochromator to disperse or separate the radiation by wavelength. Instead, a whole single-beam spectrum is generated all at once. The intensities of all of the wavelength elements are analyzed simultaneously. Since all the radiatio...
A wavelength band refers to a specific range of wavelengths within the electromagnetic spectrum that are used for transmitting data in optical communication systems, such as TWDM-PON and PtP WDM-PON. The bands are defined based on the requirements of the system and the capabilities of the transmi...
Wavenumber measurements of the transitions with accuracy about 6.6 × 104 cm1 are made with the help of a precision wavemeter calibrated to the accurate C2H2 frequency references in the 1.5-μm wavelength region. Molecular constants are obtained by making the least-squares fits of the measured ...
The infrasound frequency (f < 20 Hz) of a wavelength considerably longer than the sample cell size results in uniform pressure across the entire cell. This simplifies the Rayleigh-Plesset equation, describing the dynamics of a spherical bubble in an incompressible fluid into the Young-Laplace ...
B. G. Casimir effect: Lamb shift: Example: Light of wavelength 632.8 nm is incident on an extremely fast shutter that chops the beam into pulses. The shutter stays open for only 1.5×10-9 s. What is the approximately minimum range of wavelengths ∆λin the light pulses that pass the ...
(right).b, MIM cavity optical linewidth as a function of wavelength. The blue circles indicate measured optical cavity linewidths. The red circle indicates the optical mode used for experiments. The modulation of the cavity linewidth is because of the presence of the membrane in the cavity. ...
the single-wavelength coherent polarization division multiplexing of 400 GHz will expand from 80 wavelengths to 120 wavelengths in C-band as well as further expand to L-band. This is expected to increase per-fiber capacity to 100 Tbit/s, which is adequate to support connections at million-serv...
We have developed an open-source software package, Open-source Seismic Wave Propagation Code (OpenSWPC), for parallel numerical simulations of seismic wave propagation in 3D and 2D (P-SV and SH) viscoelastic media based on the finite difference method in local-to-regional scales. This code is...
An example of a deterministic nonlinear wave propagation model is the open-source code developed by Centrale Nantes HOS-OCEAN [DUC 07]. On the other hand, the WAVEWATCH III [WAV 16] code constitutes an example of a spectral wave model. For a presentation of deterministic wave propagation ...
Defining the tsunami height, for example, is obvious, while defining tsunami magnitude may be somewhat controversial. The tsunami magnitude evaluates the size of a tsunami, and the tsunami intensity evaluates the consequences of the tsunami event from location to location. 2.3.1. Tsunami height The...
