PURPOSE:To obtain a modified polystyrene resin having excellent heat resistance, chemical resistance, optical transparency and processability and a low refractive index by fluoroalkylating a polystyrene with a perfluoroalkanoyl peroxide. CONSTITUTION:A polystyrene (desirably of an average MW in the range ...
It is possible to form additional layers on and under the film with a low refractive index of the present invention to enhance its functions. For example, an adhesive layer to endow an adhesive property; a primer layer; or other layers to endow such functions as an antistatic property, abras...
These devices are incorporated into low refractive silicon oxynitride (SiON) waveguides, which despite being a low refractive index material, is still CMOS compatible. This material (SiON) can also be deposited onto glass substrates ena- bling rear side light coupling which is useful for large ...
The evanescent wave is small because the refractive index difference of 0.78 between the core disk and cladding air is relatively high. Figure 5(b) shows the intensity profile of the x-z cross-section of the printed and etched microdisk model. This result revealed that the micro- disk ...
1(a). The linear refractive index of the film is 1.59. Because of the low refractive index contrast between the film and air, it is not a good candidate for the design of PhC structures with a complete band gap [33–35], and the cavity here is mainly based on the directional ...
At the border of the refractive index, the fuzzy boundary model was adopted for high accuracy and the absorbing boundary condition was used.

The optical properties and electrical resistivities of the films were determined by spectroscopic ellipsometry (SE) and four-point probe measurements. The highly transparent (ca. 94% in the visible region) films had a refractive index of 2.01–2.05 and a resistivity of 2.5–3 mΩ·cm. 展开 ...
A low-pressure neural contact structure for contact with neural tissue, for example, neural tissue of the retina within which are ganglion cells to be electrically stimulated. The contact structure comprises a first portion for attachment to a first bodily location, such as the inner surface of ...
(Fig.6). To minimize miss-matching in the refractive index when imaging deep inside the worm, we used a glycerol objective lens13. We imaged a volume of 256 µm3to observe the entire anchor cell in about 60–80 s, which is less than a third of regular RESOLFT recording. Only ...
EXAMPLE 29 Conditions were as described above for Example 28. The Si--O--Si stretching frequency, and the refractive index of the films are both depicted in FIG. 29 as functions of the flow rate ratio of CF4 to Si2 H6. As the CF4 ratio increased, the peak frequency increased, from 105...
