penetration depth

[‚pen·ə′trā·shən ‚depth]
(cryogenics)
The depth beneath the surface of superconductor in a magnetic field at which the magnetic field strength has fallen to 1/ e of its value at the surface.
(electricity)
In induction heating, the thickness of a layer, extending inward from a conductor's surface, whose resistance to direct current equals the resistance of the whole conductor to alternating current of a given frequency.
(engineering)
The greatest depth in an ultrasonic test piece at which indications can be measured.

The penetration depth is dependent on various factors but mostly the ground conductivity and the EM wave frequencies (Yaccup and Brabham, 2012), when the quality of data acquired is influenced by the ambient electromagnetic noise.
Moreover, these devices have an adjustable needle and electrode penetration depth allowing clinicians to treat tumors of varying dimensions to perform minimally invasive intratumoral immunotherapy.
The higher the energy of incoming ions, the higher will be the penetration depth of the ions into the substrate.
After the sectioning, the dye penetration depth measurements were done for each specimen occlusally and gingivally with a periodontal probe in mm with the aid of magnifying lens.
[13] using penetration depth and calorimeter absorbed energy measurements, a correlation between edge surface roughness and absorption in welding structural steel in a buttjoint setup was observed.
The advantage of sample rotation is that imaging from the side into the sample and rotation of the sample by 180[degrees] doubles the penetration depth. In addition, the Horizontal 2-Photon Microscope enables a good resolution in all dimensions and the possibility of tomographical reconstruction.
Quantitative results such as penetration depth, residual depth, critical load, tangential force, and acoustic wave emission can be obtained as a function of normal load (progressive load scratch tests) and scratch length (constant load scratch tests).

Investigations had been carried out in order to examine the effect of the heating time, the penetration depth of the steel pin into the plastic plate, the surface condition of steel (average surface roughness) and the time elapsed between joining and tearing.
Roemhefd says its rnagnetic clamping technology is based on the principle of a permanent electric magnet, meaning it is safe even in the event of a power outage and, with a penetration depth of 15 to 20mm, does not impact on production.
However, these tests took the displacement of the tip as the penetration depth and neglected the compressive deformation of the spheres.
