Wave breaking is important for understanding of both sea wave dynamics and microwave scattering/emission of the ocean. Experimental studies of breaking waves are mostly related to tank measurements and to a lesser extent to field observations [1, 2]. Theoretical results regarding wave breaking are mostly obtained by numerical simulation [3]. Comparison of those with tank experiments leads to th...

The primary focus of this research is to use large-eddy simulation (LES) and large-wave simulation (LWS) to obtain improved physical understanding of wind-wave-ocean interactions, based on which we aim to develop effective models of wind input and whitecapping dissipation for phase-resolving, nonlinear wave-field simulation at large scales. Our ultimate goal is to establish a numerical capabili...

A simulation program which provides insight in the vibrational properties of resonant mass gravitational radiation antennas is developed from scratch. The requirements that are set necessitate the use of an explicit nite element kernel. Since the computational complexity of this kernel requires signi cant computing power, it is tailored for execution on parallel computer systems. After validati...

With the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. Many site-specific methods have been proposed for modeling indoor radio channels. Among these methods, the ray tracing algorithm and the finite-difference time domain (FDTD) method are the most popular ones. The ray tracing approach ...

Steep, short-crested waves, as well as a large variety of three-dimensional propagating wave patterns have been created in laboratory, utilizing a plunging half-cone. Monochromatic waves, over a range of frequencies and amplitudes through breaking and including soliton wave groups near resonance, have been observed and studied in a small wave flume. This monochromatic wavemaker creates complex ...
