As part of the ongoing effort at NIST to develop a microwave brightness temperature standard, we are exploring the electromagnetic and thermal characteristics of microwave calibration targets. Part of this effort is focused on measuring the electromagnetic properties of absorber materials used in the construction of microwave calibration targets. Improved materials characterization would also support applications of absorber materials beyond their use for calibration targets; for example, anechoic chamber design would benefit from this improved understanding.
