Terahertz frequency-domain 4 × 4 Mueller matrix ellipsometer instrument designed for high-frequency magnetic resonance measurements
We report a Mueller matrix ellipsometer design using dual continuously rotating anisotropic meta wave plates, which determines the full set of Mueller matrix elements in the terahertz spectral range. The instrument operates in the frequency domain and employs a frequency tunable, solid state synthesizer based, continuous wave terahertz source with sub-MHz bandwidth. The implemented source permits
