RF sensing is essential for defense, aerospace, and industrial monitoring, yet classical solutions struggle with miniaturization and interference. NV centers in diamond enable direct detection of RF and microwave fields via quantum spin transitions, offering broadband capability and high sensitivity at room temperature. This approach eliminates the need for complex electronics and shielding, allowing lightweight, scalable RF sensing for drones, distributed networks, and secure communication monitoring. NV-based RF sensors combine precision with portability, opening new possibilities for electromagnetic surveillance and infrastructure protection.
