Skin Depth

Some articles on skin depth, depth, skin:

Helicon (physics)
... an electromagnetic wave would experience a very thin skin depth in a metal the electric or magnetic fields are quickly reflected upon trying to enter the metal ... (Hence the shine of metals.) However, skin depth depends on an inverse proportionality to the square root of angular frequency ... Thus a low frequency electromagnetic wave may be able to overcome the skin depth problem, and thereby propagate throughout the material ...
Surface Plasmon - Propagation Length and Skin Depth
... At low frequencies, the SPP penetration depth into the metal is commonly approximated using the skin depth formula ... Surface plasmons are very sensitive to slight perturbations within the skin depth and because of this, surface plasmons are often used to probe ...
Aluminium Foil - Uses - Electromagnetic Shielding
... of the foil, and the frequency (which determines the skin depth) ... The shielding effectiveness is dependent upon the skin depth ... A field traveling through one skin depth will lose about 63 percent of its energy (it is attenuated to 1/e = 1/2.718.. ...
Skin Effect - Cause
... That decline in current density is known as the skin effect and the skin depth is a measure of the depth at which the current density falls to 1/e of its value near ... Over 98% of the current will flow within a layer 4 times the skin depth from the surface ... The skin effect has practical consequences in the analysis and design of radio-frequency and microwave circuits, transmission lines (or waveguides), and antennas ...
Tesla Coil - High Frequency Electrical Safety - The 'skin Effect'
... This is often erroneously attributed to skin effect, a phenomenon that tends to inhibit alternating current from flowing inside conducting media ... was thought that in the body, Tesla currents travelled close to the skin surface, making them safer than lower frequency electric currents ... Although skin effect limits Tesla currents to the outer fraction of an inch in metal conductors, the 'skin depth' of human flesh at typical Tesla coil frequencies is still of the order of 60 inches ...

Famous quotes containing the words depth and/or skin:

    Nature seems to have treasured up the depth of our mind talents and abilities that we are not aware of; it is the privilege of the passions alone to bring them to light, and to direct us sometimes to surer and more excellent aims than conscious effort could.
    François, Duc De La Rochefoucauld (1613–1680)

    Anyone who tries to keep track of what is happening in China is going to end up by wearing all the skin of his left ear from twirling around on it.
    Robert Benchley (1889–1945)
