This short theoretical work discusses some problems of finding of the suitable eigenvalues and eigenvectors. The eigenvalues and eigenvectors represent the solutions of the coupled equations of motion written in the well-known tensor form. These coupled equations of motion describe shear-horizontal (SH) wave propagation in the transversely isotropic piezoelectromagnetic materials of class 6mm when the SH-wave propagation is coupled with both the electrical and magnetic potentials. It is stated that as many as six eigenvalues can be soundly found for the problem. The problem is that some eigenvalues result in the corresponding certain eigenvectors and some eigenvalues allow existence of uncertain eigenvectors that can be chosen by a researcher. This uncertainty allows researchers to choose several certain forms for the uncertain eigenvectors. It is discussed that the author of this report has used the certain forms for the uncertain eigenvectors that are naturally coupled with the ce...
