Distributed acoustic sensing of microseismic sources and wave propagation in glaciated terrain

Parallel implementation of underwater acoustic wave propagation using beamtracing method on graphical processing unit

The mathematical modeling of the acoustic wave propagation in seawater is the basis for realizing goals such as, underwater communication, seabed mapping, advanced fishing, oil and gas exploration, marine meteorology, positioning and explore the unknown targets within the water. However, due to the existence of various physical phenomena in the water environment and the various conditions gover...

Acoustic Wave propagation through multilayer Thue-Morse structures containing two, three and four materials of Cu, Al, MgO and Pb

In this paper, the acoustic wave propagation in multilayer Thue-Morse structures has theoretically been studied. The composing layers were assumed do be Cu, Al, Mgo and Pb materials. Two, three or four different materials have been used in a typical structure. By using a perpendicular incident acoustic wave, the transmission coefficient was calculated and then by its old, the frequency gaps was...

Commission F : Wave propagation and Remote Sensing

F1.1 Terrestrial Fixed Radio Systems Active studies of rain attenuation characteristics are continuing for developing broadb quasi-millimeter wave band. It is based on a trend that the use of microwave band gradually from the fixed use to the mobile use. Results of those stu and systems above has been changing dies will be reflected in developing a multipoint-to-multipoint system, a mesh type w...

Commission F: Wave Propagation and Remote Sensing

A fixed wireless access (FWA) system enables to provide a broadband wireless access service with a user bit-rate of more than 10Mbps. Propagation studies have been carried out to clarify the multipath characteristics in several environments and frequency bands for developing that system. A 5-GHz band is expected to be available for wireless access systems and a residential area is an important ...
