In addition, EC variable solar reflectance coatings (VSRCs) were built on polyethylene terephthalate (PET) film. The average reflection of the VSRC in a visual spectral range was 63% in the bleached condition and 20% in the colored condition. Thermal analysis shows that a combination of VECs ...
internal reflectancediffuse reflectancecoatingpolymermid-IRradiative heat transferA simple method to evaluate the RMS beam emittance is described. We obtained a relation between the beam parameters and the RMS width of the profile which can be measured by a beam profile monitor and this relation was...
Finally, the contrast between the refractive indices of two consecutive layers should be as large as possible to increase the reflectance at the interfaces between the layers and the reflection bandwidth. 2.2. Deposition of the Films and Fabrication of the Optimized SRD Structure Conventional magnetron...
