The working group 2.21 is performing research on new measurement and calibration techniques in the field of radio frequency engineering. The following topics are covered:
Extension of measurement capabilities into the THz frequency range
Traceability of digital signal properties
Dosimetry of non-ionizing radiation
Electromagnetic Wave propagation in future THz communication systems
Advanced remote-controlled airborne sensor systems – arcass
