Consistent description of radiation damping in transient soil-structure interaction
… by an unbounded soil-domain and thus by radiation damping. This radiation damping arises due to wave propagation from the excited structure into the subsoil and may lead to a reduction of the structural response. A consistent description of this radiation damping has been carried out by …

Effects of Radiation Damping in Extreme Ultra-intense Laser-Plasma Interaction
… get energy more than 100 MeV and start to emit radiation strongly. Resultingly, the damping of electron motion can become large. In order to study this problem we developed a code to solve a set of equations describing the evolution of a strong electromagnetic wave interacting with a single …

Untangling energy dependent radiation damping and chemical interface damping in gold nanorods
… for practical applications. Specifically, radiation damping and chemical interface damping are crucial in plasmonic sensing and plasmon-enhanced optoelectronics. However, in systems where it is desirable to study both radiation and chemical interface damping, these terms can become …

Influence of soil parameters on the motion of rocking walls
… One of these uncertainties is the effect of radiation damping on the motion of the system. Existing estimations for the radiation damping use an equivalent damping ratio, which was actually derived for a rocking block that is not connected to any structure. The formula for this equivalent …

Exploring the Limits of Boundary Element Methods for Wave Energy Converter Hydrodynamics
… The representations– excitation, added mass, and radiation damping in up to six degrees of freedom– define and scale the forces in the equation of motion for these devices, and can be used in time-domain modeling tools to predict the behavior of the system in response to waves. It is important for …

Response of Venice storm gates to incident waves
… The amplitude of gates motion, added mass and radiation damping are reported for a large interval of periods. Synchronous resonance of the gates is found and the occurrence of negative added masses is reported and discussed.

Acoustic resonators with integrated microfluidic channels for ultra-high Q-factor: a new paradigm for in-liquid gravimetric detection
… that eliminates nearly all dissipation and damping from sample liquids, rendering a significant improvement in Q-factor for in-liquid gravimetric detection. We constructed rigid microfluidic channels to confine liquids and the associated acoustic energy, thereby eliminating acoustic …

Structural vibrations in acoustic fields
… modes. Results are given of the acoustic radiation damping.<br/><br/>Wide frequency band space correlation measurements of the pressure field close to a two-inch diameter cold air jet are described. The results are shown to be consistent with the hypothesis that the pressure field close to …

Contribution to kinematic and inertial analysis of piles by analytical and experimental methods
… to the dynamic interaction phenomenon, such as radiation damping and wave propagation in in homogeneous media. The main goal of the theoretical effort lies in the derivation of solutions in closed - form for: (i) the static stiffness and the dynamic impedances (dynamic stiffness and damping …
