Seismic Metamaterial
Seismic metamaterials are a type of material that is used to manipulate and control seismic waves, which are generated during earthquakes and other seismic events.…
Accelerometers and Dark Matter Sensors might be Improved by Quantum Entanglement
The “spooky action at a distance” that once alarmed Einstein may soon become as commonplace as the gyroscopes used in today’s smartphones to monitor acceleration.…
Dark Matter-Nucleon Interactions are Now a Focus of the DarkSide Experiment
The complex DarkSide project uses a dual-phase physics detector at the subterranean Gran Sasso National Laboratory to look for interactions between dark matter particles in…
Tunable Metamaterial
A tunable metamaterial has properties that can be changed by an external stimulus such as an electric or magnetic field, temperature, or strain. Metamaterials are…
Nonlinear Metamaterial
A metamaterial is an artificial material with properties that are not found in naturally occurring materials. A nonlinear metamaterial is a material that has been…
Photonic Metamaterial
A photonic metamaterial (PM), also known as an optical metamaterial, is a type of electromagnetic metamaterial that interacts with light at wavelengths ranging from terahertz…
P Wave – in Seismology
In seismology, a P wave (primary wave or pressure wave) is one of two types of elastic body waves known as seismic waves. Because P…
Waves in Plasmas
Waves in plasmas are electromagnetic waves that travel through an ionized gas containing charged particles such as electrons and ions. Plasmas can be found in…
Acoustic Attenuation
The reduction of sound energy as it propagates through a medium is referred to as acoustic attenuation. Sound wave attenuation can occur due to a…
Thermionic Converter
A thermionic converter is made up of a hot electrode that thermionically emits electrons to a cooler electrode, producing useful electric power output. Caesium vapor…
Acoustic Dispersion
Acoustic dispersion is the phenomenon in which the speed of sound waves through a medium varies with frequency. In other words, different frequencies of sound…
