Underwater acoustic beam dynamics

The Journal of the Acoustical Society of America, 2009
Ray- and mode-based theoretical predictions of the spreads of directionally narrow beams are presented and compared to parabolic-equation-based simulations in deep-ocean environments. Both the spatial and temporal spreads of beams are considered. The environments considered consist of a range-independent deep-ocean background sound channel on which a ...

Dynamic control of plasmonic beams

Optics Letters, 2019
We experimentally demonstrate dynamic, electrically controlled shaping of plasmonic beams, propagating at the boundary between a metal and a dielectric, by using the thermo-optic effect. The concept is based on selectively heating a specific region in which the plasmonic beam passes by injecting electrical current to an isolated metal layer. This leads

Dynamic Beam Shaping

Medical Dosimetry, 1990
Computer control of independent collimator jaw positions and dose is combined with multiple-field summation techniques to design optimized radiation field profiles. Clinically relevant examples are shown for dynamic wedges and compensated mantle fields. Calculation, measurement, and verification techniques are discussed.
