Resonant frequencies of two simultaneously Co coated MCLs: anisotropic elasticity
of the films. (a) (Top) Resonant frequencies for the PA-MCL: ν_{o }representing the resonant frequency before the coating process and ν_{(CPA-MCL) }representing the resonant frequency after the Co coating process with deposition time
t = 4 min. ν^{2}_{(CPA-MCL)}/ν_{o}^{2 }= 0.9778. (Bottom) Resonant frequencies for the simultaneously coated PE-MCL: ν_{o }representing the resonant frequency prior to the coating process and ν_{(CPE-MCL) }representing the resonant frequency after the coating process; ν^{2}_{(CPE-MCL)}/ν_{o}^{2 }= 0.9864. (b) Resonant frequencies of the two simultaneously coated MCLs coated consecutively for
4 min: that is, for a total deposition time of 8 min. ν^{2}_{(CPA-MCL)}/ν_{o}^{2 }= 0.9532 and ν^{2}_{(CPE-MCL)}/ν_{o}^{2 }= 0.9768. Note the significant difference between the PA-MCL and PE-MCL ratios for
the two cases and the difference between these results and those displayed in Figure
2.
