skin depth

[′skin ‚depth]
(electromagnetism)
The depth beneath the surface of a conductor, which is carrying current at a given frequency due to electromagnetic waves incident on its surface, at which the current density drops to one neper below the current density at the surface.

Additionally, skin effect at higher frequencies, which causes the effective resistance of the conductor to increase at higher frequencies where the skin depth is smaller, worsens the insertion-loss performance of the rough surface of copper traces on a PCB.
The skin depth ([delta]), power penetration depth ([D.
where [delta] is the skin depth, which is frequency dependent.
This simplifies the modeling of materials with a very thin skin depth (compared to the size of the model) by replacing the volume elements in a conducting region with surface elements.
With a sharp knife, make cuts in the legs to skin depth, then add the legs to the bowl, combine and marinate in the fridge, covered, overnight.
When the thin film is much thicker than its skin depth and absorption dominates its EMI shielding.
With the patient sitting and the thoracic spine flexed forward (increasing convexity) the epidural space at the T6/7 level was detected by a loss of resistance to saline at skin depth 8 cm using an 18 gauge B.
To complicate matters, skin depth varies by the frequency of the signal.
Field penetration into materials such as concrete may be summarized by skin depth.
conductivity, magnetic permeability and the presence of defects, the frequency of the input signal determines the so-called skin depth of ECs as well.
On the other hand, the increase in frequency leads to the reduction of skin depth and consequently to the rise of temperature of the brass flange.
The range of skin depth for the thin-wall ductile iron plates investigated was between 0.
