Harmonic Generation in an Electromagnetic Wave

ZAMP Zeitschrift für angewandte Mathematik und Physik, 1973
A plane electromagnetic wave is propagated in a non-linear non-dissipative isotropic dielectric. A method is given for the calculation of the change in the amplitudes and phases of harmonics of all orders, as the wave progresses, for any specified dependence of the dielectric constant on the magnitude of the electric field and for any initial wave form.

Frozen waves: experimental generation

Optics Letters, 2012
Frozen waves (FWs) are very interesting particular cases of nondiffracting beams whose envelopes are static and whose longitudinal intensity patterns can be chosen a priori. We present here for the first time (that we know of) the experimental generation of FWs.

Shock wave generator for generating an acoustical shock wave pulse

The Journal of the Acoustical Society of America, 1991
A shock wave generator has a focusing stage wherein a number of different lenses having respectively different concentrating characteristics are accommodated, and which can be selectively introduced transversely into the path of the shock wave pulse, by linear displacement or by pivoting.

The generation of edge waves by a wave-maker

Physics of Fluids, 1996
A theory is developed to describe the generation of edge waves on a uniform beach by a wave-maker. The theory is based on the linear shallow-water equations. The wave-maker is a vertical plate spanning between the shoreline and the paddle axis offshore, and oscillates periodically in the alongshore direction.

Wave Generation in the Terrestrial Magnetosphere

Space Science Reviews, 1983
The Earth’s magnetosphere supports a large variety of plasma wave phenomena covering nine decades of frequency from 10-3 Hz to 10-3 Hz. Understanding why waves occur when and where they do involves sorting out the subtle interplay between the background macroscopic features of the system, the geometry, the large scale flow, etc., and the microphysics ...

Generation and Thermalization of Plasma Waves

The Physics of Fluids, 1958
Generation of hydromagnetic and ion cyclotron waves by an induction coil is considered for a cylindrical plasma in a uniform confining magnetic field. Resonance widths are calculated and power absorption is calculated and compared to ohmic losses in the induction coil.

A triangular wave form generator

Talanta, 1969
A simple generator for triangular waveforms is described. It uses two operational amplifiers to give triangular waves between 0 V and a preselected voltage. The scan rate and limit can be varied independently.

Detection and Generation of Gravitational Waves

Physical Review, 1960
Methods are proposed for measurement of the Riemann tensor and detection of gravitational waves. These make use of the fact that relative motion of mass points, or strains in a crystal, can be produced by second derivatives of the gravitational fields.

Laboratory Generated Waves and Wave Theories

Journal of the Waterway, Port, Coastal and Ocean Division, 1980
Tests are carried out in a wave tank to record the waves, the water pressures, and the horizontal and vertical water particle velocities. The water depth is such that the waves generated during the test cover the deep, intermediate and shallow water ranges. In the intermediate and shallow water range the soliton effects are observed. In deep water, the
