Acoustic levitation

Index Acoustic levitation

Acoustic levitation (also: Acoustophoresis) is a method for suspending matter in a medium by using acoustic radiation pressure from intense sound waves in the medium. [1]

Acoustic radiation pressure

Acoustic radiation pressure is the apparent pressure difference between the average pressure at a surface moving with the displacement of the wave propagation (the Lagrangian pressure) and the pressure that would have existed in the fluid of the same mean density when at rest.

Acoustic tweezers

Acoustic tweezers is a technology that is able to control the movement of objects by sound waves.

Aerodynamic levitation

Aerodynamic levitation is the use of gas pressure to levitate materials so that they are no longer in physical contact with any container.

Buoyancy

In physics, buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object.

Electrical conductor

In physics and electrical engineering, a conductor is an object or type of material that allows the flow of an electrical current in one or more directions.

Electromagnetism

Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.

Electrostatic levitation

Electrostatic levitation is the process of using an electric field to levitate a charged object and counteract the effects of gravity.

Magnetic levitation

Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields.

Optical levitation

Optical levitation is a method developed by Arthur Ashkin whereby a material is levitated against the downward force of gravity by counter forces stemming from photon momentum transfer.

Radiation pressure

Radiation pressure is the pressure exerted upon any surface due to the exchange of momentum between the object and the electromagnetic field.

Sound

In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.

Ultrasound

Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing.
