Calculation of Field Amplitude Distribution of Ultrasonic Wave Beam in Moving Media

The results of acoustical (ultrasonical) wave beam amplitude distribution modeling in free space and in application of moving media are presented. The propagation of ultrasonical wave has been considered in x-y coordinate plane for infinitive plate radiator restricted on x – axis. The shift of ultrasonical beam field for different distributions of moving media velocity projections in the plane of wave propagation is considered.

Calculation of Focusing Spin Wave Transducers Using the Method of Micromagnetic Simulation

Background and Objectives: Researches in the field of electronic circuit development for microwave informational systems based on magnetization oscillations and waves have been performing since the 1960s of the last century. The surge of interest in spin waves (SW) during the last decade is caused by the perspective to use SW as information carriers on the sub-micromagnetic and nanometer scale that leads to the fabrication of devices on magnonic principles and a significant miniaturization of spin-wave devices.
