The invention relates to surface wave filters in double ring. It comprises reception transducers (304, 314) of such filter which are arranged on either side of the emission transducer (301) with respect to the emission axis of acoustic waves. Said waves are reflected to said transducers by ...
<p><strong>Step-by-Step Solution:</strong></p><p>1. <strong>Definition of Transverse Wave:</strong> A transverse wave is a type of wave in which the particles of the medium move perpendicular (at right angles) to the direction in which the wave travel
For a rectangular or very wide channel we have Fr = V co = V (g )y 1/2 where y is the water depth and co= (gy).5 and co = the speed of a surface wave as the wave height approaches zero. There are three flow regimes of incompressible flow. These have analogous flow regimes ...
Single Interdigital Transducer as Surface Acoustic Wave Impedance Sensor In this paper, a novel SAW-based impedance sensor type is introduced which uses only one interdigital electrode transducer (IDT) simultaneously as SAW generator and sensor element. It is shown that the amplitude of the reflected...
Gamma-ray Burst Afterglow Model Fitting Based Directly on Blast Wave Simulations Gamma-ray burst are the most luminous explosions in the universe, seen as sudden flashes in gamma-rays, often followed by a long-lasting afterglow signal detected from X-rays to radio. On the one hand, afterglow ...

A method determines the layer thickness of a TBC coating of at least one blade of a non-positive-displacement machine. To this end, at least one electromagnetic wave is emitted to the surface of the at least one blade, the at least one e... T Bosselmann,K Huber,A Schicht,... - US...
10x1010 ohm or less in surface resistance is formed on the back surface of a light-transmitting high-molecular substrate having laminated thereon a semi-transmitting reflective layer composed of a light-transmitting deposited metal film or metal thin film, to thereby form a semi-transmitting ...
