How moving the antenna beam affects its shape for a lens antenna
What is it about?
A Luneburg lens is a classical lens that focuses a plane wave to a point, or converts a point source to a plane wave. It is usually implemented as a spherical graded index lens, but can be made flat using spatial transformations (transformation electromagnetics), at the cost of changing the material properties as a function of space. This was implemented using composite dielectrics and tested using a commercially-available transceiver kit at 60 GHz, for potential use in 5G and beyond.
Why is it important?
Demonstrating broadband, low-loss, and compact beam-steering gives a route for future wireless networks at high frequencies.
