Washington, April 20 : An international team of scientists has reported an innovative method for controlling light on the nanoscale by adopting tuning concepts from radio-frequency technology, which opens the door for antenna-based applications, including highly sensitive biosensors and extremely fast photodetectors.
These applications could play an important role in future biomedical diagnostics and information processing.
An antenna is a device designed to transmit or receive electromagnetic waves.
Radio frequency antennas find wide use in systems such as radio and television broadcasting, point-to-point radio communication, wireless LAN, radar, and space exploration.
