To achieve this, custom made, reduced aperture, sample holder flanges were used that reduce the waveguide's excessive cross-sectional dimensions, resulting in reduced sample fabrication costs. Additionally, MatLab code was developed to implement the rigorously derived modal-analysis solution that accommodates induced, higher-order transverse electric and transverse magnetic modes and accurately extract the reduced test sample's constitutive parameters. Experimental results using various test samples are compared to known, full-aperture measurements for both the reduced aperture waveguide configurations to verify the theoretical analysis. A differential error analysis is also performed for each configuration in an attempt to estimate the error associated with test sample thickness, aperture dimensions, and sample placement uncertainties.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Derek R.
