Basic Principles of
Fresnel Antenna Arrays
The classical Fresnel lens is different from the shaped dielectric lens in that the
phase transforming surface is broken down into Fresnel zones, or concentric
circular sections. Although the sections have discontinuities between them, each
...

Solar Cells and Their Applications
However, when closed facet spacing is used, diffraction effects can decrease the
optical efficiency of the Fresnel lens. These losses can become significant at
facet diameters around 100 μm. In addition to the loss mechanisms specific to the
...

In a binary-phase planar Fresnel lens, the phase difference between the adjacent
zones can be tuned by the applied voltage. Maximum diffraction occurs when the
phase difference is equal to an odd multiple of π while no diffraction occurs for ...

The first Fresnel lens in the world was installed at Cordouan Lighthouse in
France in 1823. The new technology was an instant success, and Europeans
moved quickly to install the Fresnel lens in their lighthouses. The United States
did not.
