Broadband, non-destructive characterisation of PEC-backed materials using a dual-ridged-waveguide probe PROJECT TITLE :Broadband, non-destructive characterisation of PEC-backed materials using a dual-ridged-waveguide probeABSTRACT:A replacement probe that utilises a twin-ridged waveguide to produce broadband, non-destructive (ND) material characterisation measurements of a good electric conductor (PEC)-backed material is introduced. The new probe possesses a bandwidth like existing coaxial probes and is structurally robust like rectangular waveguide probes. The mixtures of those two qualities create it particularly enticing for ND inspection/evaluation applications in the field. The theoretical development of the twin-ridged-waveguide probe is discussed. A magnetic field integral equation comes by applying Love's equivalence theorem and enforcing the continuity of transverse fields at the dual-ridged-waveguide aperture. The magnetic field integral equation is then solved for the theoretical reflection coefficient using the tactic of moments. The permittivity and permeability of the fabric underneath take a look at are found by minimising the foundation-mean-sq. difference between the theoretical and measured reflection coefficients using non-linear least squares. To validate the new probe, experimental results are presented of a magnetic absorbing material comparing results obtained using the new probe with those obtained employing a traditional, harmful technique. The probe's sensitivity to sample thickness, flange-plate thickness, cutoff wavenumber and measured S-parameter uncertainties is additionally investigated. Did you like this research project?
