The fundamental question answered by our backscatter radio research program is what is the minimum possible energy that a communication node must expend to transfer information wirelessly? The more you understand about conventional wireless communications, the more the answer will surprise you.
Active areas of backscatter radio research in the group include:
-
- retro-directive structures for microwave and mm-wave backscatter
- optimal RF scattering and RF harvesting antenna structures
- channel coding for long-distance/high throughput backscatter
- ambient signal scavenging
- quantum tunnel reflectors (QTRs)
- backscatter receiver design
- object-resistant and environment-resistant antenna design
