Abstract
Examples disclosed herein relate to a smart infrastructure sensing and communication system. The system includes a resonant structure formed of an array of resonant cells and attached to a glass of a smart infrastructure. The resonant structure generates a radio frequency (“RF”) signal that is shaped and steered by the array. A controller is in communication with the resonant structure to receive the RF signal.
Claims20
A smart infrastructure sensing and communication system, comprising:
- a resonant structure formed of an array of resonant cells, the resonant structure attached to a glass of a smart infrastructure and to generate a radio frequency (“RF”) signal that is shaped and steered by the array, the RF signal relayed through the glass to specific and predefined locations inside the smart infrastructure;
- and
- a controller in communication with the resonant structure to receive the RF signal.
A passive resonant cell for use in a smart infrastructure sensing and communication system of a smart infrastructure, the passive resonant cell attached to a glass in the smart infrastructure and comprising:
- a plurality of glass layers;
- a ground metal layer;
- and
- a plurality of metal patches to generate a reflection of an RF signal received from outside of the smart infrastructure, the reflection of the RF signal relayed through the glass to specific and predefined locations inside the smart infrastructure.
An active resonant cell for use in a smart infrastructure sensing and communication system, the active resonant cell attached to a glass in the smart infrastructure and comprising:
- a metamaterial cell having a conductive outer portion surrounding a conductive area, the metamaterial configured on a dielectric layer and a glass substrate and to relay an RF signal received from outside the smart infrastructure through the glass to specific and predefined locations inside the smart infrastructure;
- and
- a voltage controlled reactance device placed between the conductive outer portion and the conductive area.
