Wave-number spectrum of electrocorticographic signals

Physical Review E, 2003
A physiologically based continuum model of corticothalamic electrodynamics is generalized and used to derive the theoretical form of the electrocorticographic (ECoG) wave-number spectrum. A one-dimensional projection of the spectrum is derived, as is the azimuthally averaged two-dimensional spectrum for isotropic and anisotropic cortices. The predicted

Linearization of the Wave Spectrum: A Comparison of Methods

Volume 2A: Structures, Safety, and Reliability, 2020
Abstract The relative contributions of free waves and bound waves to the formation of an extreme wave event remains a topic of interest in offshore engineering. A variety of methods have been proposed for identifying and removing the bound wave components.

Simulation of Ocean Waves With Spectrum‐Based Wave Particle

Computer Animation and Virtual Worlds
ABSTRACTThe spectrum‐based method, usually referred to as the Fourier approach, is considered to be an efficient solution for synthesizing and visualizing realistic ocean waves, and is widely used in films and video games. It is based on a spectra function describing the distribution relationship between the wave energies and various individual waves ...

The Effect of Wave Breaking on the Wave Energy Spectrum

Journal of Physical Oceanography, 1987
Abstract The effect of wave breaking on the wave energy spectral shape is examined. The Stokes wave-breaking criterion is first extended to random waves and a breaking wave model is established in which the elevation of breaking waves is expressed in terms of that of the original ideal waves, which are assumed to be stationary and Gaussian.

Spectrum of axisymmetric torsional Alfvén waves

The Physics of Fluids, 1978
The spectrum of axisymmetric torsional Alfvén waves propagating in a cylindrical, nonuniform, resistive plasma waveguide has been analyzed by a method of singular perturbations. It is indicated why some experiments show a continuous spectrum and others a discrete spectrum.

Millimeter-Wave Spectrum of Formic Acid

The Journal of Chemical Physics, 1956
The investigation of the Ra branch of the formic acid rotational spectrum has been extended up to J = 9 around 1.5 mm wavelength. The centrifugal distortion corrections have been studied in some detail partly by means of sum rules and partly by power series expansions and other approximate methods.

Plane wave spectrum representation of electromagnetic waves

2007
The theoretical development of planar near-field antenna measurements is usually based on this plane wave spectrum (PWS) representation of electromagnetic (EM) fields. This generalized interpretation can be shown to stem from the free-space solution of the scalar wave equation, which itself follows directly from classical EM theory and Maxwell's ...
