Energetic Comparison of Linear Fresnel and Parabolic Trough Collector Systems [PDF]
Within the last years, Linear Fresnel (LF) collector systems have been developed as a technical alternative to parabolic trough collector (PT) systems. In the past, LF systems focused on low- and medium temperature applications.

High-Transmission Neutron Optical Devices Utilizing Micro-Machined Structures
Neutrons are a powerful probe in material science with unique penetrating abilities. A major challenge stems from the fact that neutron optical devices are limited to refractive indices on the order of n≈1±10−5.

Design of an improved Fresnel prism
Based on the optimization of the optical material and internal reflection angle, we designed a model of improved Fresnel prism that is insensitive to the angle of incidence. In this device, the incident light is reflected twice at the same internal reflection angle on the interface between two kinds of glass and the air.

Calculate The Resonance Angle of Surface Plasmon Resonance Gold film Configured with Kretschmann
The current work includes measurements of the resonance angle and reflectance for p-polarization of the electric field by using the Fresnel equation at a given length. Gold's surface plasmon wave can be seen at the metal-to-air boundary.
