Coaxial

In geometry, coaxial means that two or more three-dimensional linear forms share a common axis.

Electrical impedance

Electrical impedance is the measure of the opposition that a circuit presents to a current when a voltage is applied.

Neutron probe

A neutron probe is a device used to measure the quantity of water present in soil.

Oscillation

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states.

Polyvinyl chloride

Polyvinyl chloride, also known as polyvinyl or '''vinyl''', commonly abbreviated PVC, is the world's third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene.

Relative permittivity

The relative permittivity of a material is its (absolute) permittivity expressed as a ratio relative to the permittivity of vacuum.

Soil

Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.

Standing wave

In physics, a standing wave – also known as a stationary wave – is a wave which oscillates in time but whose peak amplitude profile does not move in space.

Time-domain reflectometer

A time-domain reflectometer (TDR) is an electronic instrument that uses time-domain reflectometry to characterize and locate faults in metallic cables (for example, twisted pair wire or coaxial cable).

Transmission line

In communications and electronic engineering, a transmission line is a specialized cable or other structure designed to conduct alternating current of radio frequency, that is, currents with a frequency high enough that their wave nature must be taken into account.
