Highly confined low-loss plasmons in graphene-boron nitride heterostructures [PDF]
, 2014 Graphene plasmons were predicted to possess ultra-strong field confinement and very low damping at the same time, enabling new classes of devices for deep subwavelength metamaterials, single-photon nonlinearities, extraordinarily strong light-matter ...

Damping rates of hot Giant Dipole Resonances [PDF]
, 1998 The damping rate of hot giant dipole resonances (GDR) is investigated. Besides Landau damping we consider collisions and density fluctuations as contributions to the damping of GDR.

Dynamical shift condition for unequal mass black hole binaries
, 2010 Certain numerical frameworks used for the evolution of binary black holes make use of a gamma driver, which includes a damping factor. Such simulations typically use a constant value for damping.

Damping of gravitational waves by matter
, 2017 We develop a unified description, via the Boltzmann equation, of damping of gravitational waves by matter, incorporating collisions. We identify two physically distinct damping mechanisms -- collisional and Landau damping.

Determining Vibration Frequency and Damping of Metal Beams Using Image Processing Method [PDF]
Computational Engineering and Physical ModelingIn the present study, damping and frequency of two beams, including galvanized and steel beams, were evaluated using the image processing method. The beam supports were designed as a hinge and the intended beam was vibrated through displacements. the FFT
