Here we present a method for recovering through-thickness profiles of two texture coefficients, namely W_(400) and W_(420), in orthorhombic sheets of cubic metals. Our method is based on a careful analysis of the through-thickness resonance spectra as obtained from resonance-EMAT or laser-ultrasound measurements. Shifts in resonance frequencies are related through mathematical formulae to the profiles of the two texture coefficients in question. Resonance spectra generated by EMAT measurements on a copper sample are used to test the validity and usefulness of this theory.
