Further more the found eigenvalues have clear mechanical meaning, since they represent the attenuation of the distortional eigenmodes and may be used in the automatic meshing of approximate distortional beam elements. The magnitude of the eigenvalues thus also gives the natural ordering of the modes....
(V) that is mapped onto the orthogonal output basis (U) for the linear transformation operator,t. Therefore, the columns ofUcontain near-field eigenmodes at the upper plane of the nano-slits (see Supplementary Note2for further explanation). In addition, the physical meaning of the eigenvalue...
u = results.Eigenvectors; pdeplot(model,XYData=u(:,1)); Get Copy Code Block pdeplot(model,XYData=u(:,length(l))); This problem isseparable, meaning u(x,y)=f(x)g(y). The functionsfandgare eigenfunctions in thexandydirections, respectively. In thexdirection, the first eigenmode is ...
Notice:Only low frequencies up to 300 cycles per second are to be regarded. Higher modal frequencies lose their meaning, because the interfering effect is covered by other room acoustic effects. In audio technology we consider at reflecting walls only themodes as sound pressure maxima- that are ...
We denote this ratio |$I_A$| and argue that |$I_A\\gt 0$| when the elastic anisotropy is of entirely intrinsic origin (meaning the elastic moduli are in -sensitive to stress), and further that |$I_A$| increases for decreasing frequency for such cases. We demonstrate that |$I_A$...
