The Acoustic Index of Refraction
in the Presence of a Wave Packet.
where n is the index of refraction
of the space or vacuum that is polarized by the scalar field and its relation to the scalar field is given by (1) or (2); D is the dimension of the object that produces the scalar field; m + 1 is the number of shifting the interference pattern from bright to dark (only one shift from bright to dark if m = 0); and [lambda] is the wavelength of the laser light.
Let us consider a perturbation on the index of refraction
in the form [mathematical expression not reproducible] where [mathematical expression not reproducible] is the cutoff function defined on the interval [-R(-[??]), r].
This agreement of the experiment results and our model of the experiment shows that we can model the immersion coefficient correctly, and the coefficient depends only on the index of refraction
of the water, the window coating, and fused silica.
Also, unless otherwise specified, the index of refraction
of the surrounding medium, noted as [n.sub.0], is set to 1.5 to simulate a typical polymeric material and the wavelength of the incident radiation in vacuum, noted as [[lambda].sub.0], is fixed as 0.545 [micro]m close to the maximum sensitivity of the human eye.
Here, [bar.n] denotes the average index of refraction
, [DELTA]n(z) is the modulation depth of the grating and A0 is the reference period of the grating.
A method to determine the index of refraction
was used to calculate the optical path length difference using the reflection and through-transmission mode as shown in Table 1.
One can observe that the numerical framework we applied demonstrates the large influence of the relative index of refraction
in the nature of the electromagnetic couplings between the heterogeneities.
They then cascaded the negative index medium with a positive refractive index medium so that the complete nanostructure behaved as one with an index of refraction
Development of new technologies using metamaterials has been hindered by two major limitations: too much light is absorbed by metals such as silver and gold contained in the metamaterials, and the materials need to be more precisely tuned so that they possess the proper index of refraction
The factor by which light slows down is known as the material's index of refraction
<p>At the heart of optical networking is optical fiber, which consists of a narrow thread of glass--actually pure silicon dioxide--that's been clad with another glass that has a different index of refraction
. A light signal introduced into the central fiber is reflected off the edges of the fiber as it travels along its length and thus doesn't disperse or scatter.
