The visible frequency has been elusive because the plasma frequency of metals is the ultimate limiting condition.
12.
Many common metals have plasma frequencies in the Tardis 16 : 49, 1 August 2006 ( UTC)
13.
The Drude model applies when the restoring force component is negligible and the coupling coefficient is generally the plasma frequency.
14.
This occurs because the equivalent ( effective ) permittivity has a behavior governed by a plasma frequency in the microwave domain.
15.
Also known as the Drude Model for free electrons where is the plasma frequency and ? is the frequency of the electromagnetic radiation.
16.
They oscillate back and forth at the plasma frequency until the energy is lost in some kind of quantization of this kind of oscillation.
17.
If the frequency of the radio wave is lower than the plasma frequency, it is reflected . if it is higher, it transmit.
18.
When illuminated near its plasma frequency, the lens could be used for superresolution imaging that compensates for wave decay and resolution of the image.
19.
Subsequently, both radio emissions, near the plasma frequency, and whistler waves at much lower frequencies were seen to emerge from this region.
20.
These materials are further described as a homogeneous, isotropic, metamaterial covers near plasma frequency dramatically reducing the fields scattered by a given object.
