-  * Toki: 1) focus should be at top of lenslets; 2) require an absorbing layer below the antennas to ensure broad band and high efficiency. Conceptually, can think of an array of spider webs right below the antennas.  +  * Toki: 1) focus should be at top of lenslets; 2) require an absorbing layer below the antennas to ensure broad band and high efficiency.
