EurekAlert  October 1, 2020 To improve thermal imaging an international team of researchers (USA – Harvard University, industry, MIT, South Korea, Spain, Japan) has developed a microwave bolometer that it is capable of detecting a single microwave photon. The graphene bolometer sensor detects electromagnetic radiation by measuring the temperature rise as the photons are absorbed into the sensor. Graphene is incorporated in the microwave antenna. A key innovation in this advancement is to measure the temperature rise by superconducting Josephson junction while maintaining a high microwave radiation coupling into the graphene through an antenna. The research has found a new […]
