Novel Approach to the Study of Surface Plasmon Resonance and
... A spheroid is a quadric surface in three dimensions obtained by rotating an ellipse about one of its principal axes. Three particular cases of a spheroid are: 1) the ellipse is rotated about its major axis, the surface is a prolate spheroid; 2) the ellipse is rotated about its minor axis, the surfac ...

Acousto-Optic Devices and Applications
... When an acoustic wave propagates in an optically transparent medium, it produces a periodic modulation of the index of refraction via the elasto-optical effect. This provides a moving phase grating which may diffract portions of an incident light into one or more directions. This phenomenon, known a ...
