Parameter extraction by holographic filtering

Applied Optics, 1982
Holographic matched filter pattern recognition has been plagued by too much sensitivity to such parameters as rotation and scale. We show here how to use that sensitivity to make rapid accurate estimations of those parameters. For the particular case studied, we made signal-magnitude independent measurements of four rotation angles from -15 to +15 ...

Impact of parameter extraction methodology on variances of extracted parameter values

Solid-State Electronics, 2010
Abstract Two general classes of strategies for extraction of compact model electrical and temperature scaling parameters are identified and compared in the present paper. Applying these to extract parameters of the p–n junction depletion capacitance, we show that the reproducibility of estimated parameter values can strongly depend on the extraction ...

Extraction of metamaterial parameters

2015 IEEE 6th International Symposium on Microwave, Antenna, Propagation, and EMC Technologies (MAPE), 2015
In this paper, we present to retrieve the effective electromagnetic parameters of a metamaterial. In this retrieval method, calculated or measured scattering parameters are employed for plane wave incident obliquely on a metamaterial slab at different angles.
