AMTA Webinar : Modified Thru-Reflect-Match Polarimetric Calibration Technique for Focused Beam Systems  
Thursday, December 12, 2024 11:00 AM Eastern Standard Time (EST) - 12:00 PM Eastern Standard Time (EST)

AMTA Webinar : Modified Thru-Reflect-Match Polarimetric Calibration Technique for Focused Beam Systems

Jeffrey Massman (Phased Array Platforms and Applications, Analog Devices)

Extends the time-domain gated response isolation scheme for full polarimetric calibration with a modified Thru-Reflect-Match procedure for network analyzer self calibration where precise knowledge of the metrology standards is not required. Cross-polarization contributions from the measurement setup are neglected to simplify the procedure. A simulated cascade analysis is included to demonstrate the relative scattering parameter error of the sample under test when the measurement setup cross-polarization level is neglected. The featured calibration analysis leverages a 4x4 scattering parameter matrix notation to capture the polarimetric scattering at each cascaded stage and develops a 16-term error correction factor model to account for cross-polarization scattering contributions from the measurement sample. Finally, a wire-grid polarizer is used as a modified Match standard where a series of interrogations at multiples orientations, in combination with Thru and Reflect measurements, enables cross-polarized scattering channels to be characterized. This polarimetric self-calibration approach uses physically realizable metrology standards and accounts for all error terms for precision focus beam system measurements
