In the numerical results presented earlier the eigenfrequencies are indicated in the figures of the eigenmodes. As seen from the presented results the frequency which is near to 20 Hz is observed in the fourth eigenmode (see Fig.
This means that the eigenmode information (displacements) that corresponds to the experimental data is obtained for these DOFs only.
The [f.sub.r] and [f.sub.a] values for each eigenmode can be obtained when the relative admittance reaches peaks and troughs, respectively.
Hence, by simulating a single proposed EBG unit cell structure, an infinite periodic structure model is carried out by CSTMWs eigenmode simulator.
It is interesting that varying the value A, one strongly affects the corresponding PC and therefore the eigenmode. The fact that the power-dependent PCs can have some potential for optical signal processing is pointed out in many papers (see, e.g., [28-34]).
Numerical methods, as the most practical way of solving these problems, can be divided into three main categories: frequency domain, time domain and eigenmode or modal solvers, while the most suitable methods are solvers in frequency domain [4].
where [X.sub.mn](x) is the eigenmode of the plate in the x-direction.
The EBG's can be calculated by solving an eigenmode equation for the electromagnetic field associated to an infinite extension of the periodic surface in order to calculate the dispersion diagram (DD) [15].
Here [a.sub.j] is the expansion coefficient of [W.sup.(1)] with respect to the eigenmode [W.sub.j],
MICROWAVE STUDIO, in turn, comprises several sections: the front end, a transient solver, a time-domain transmission-line solver, a frequency-domain solver, an Eigenmode solver, an integral equation solver, a multilayer solver, and an asymptotic solver.
Multifrequency methods, where the cantilever is excited at multiple eigenmodes (not just the first eigenmode, as is done in conventional tapping AFM), has shown great promise in enhanced contrast based on material properties.
