| Outline of Final Research Achievements |
This research focused on the fact that in two-dimensional communications, where electromagnetic waves are transferred via a waveguide sheet, more functionalities can be embedded into the waveguide. As an example of our achievement, a prototype backscatter transmitter circuit achieved 3 Mb/s data rate, while RF oscillators and RF amplifiers were eliminated from the circuit, and a carrier wave (2.4 GHz, 10 dBm) was supplied in a waveguide sheet. In addition, we found a method to mitigate the degrading lowpass cutoff frequency of the larger waveguide sheet by connecting a negative capacitance circuit to the waveguide side.
