Resonant frequencies of two simultaneously Au coated MCLs: isotropic elasticity of the films. (a) Resonant frequency of an MCL before coating, νo, and the corresponding frequency, ν(CPA-MCL) of the same MCL (now referred to as the CPA-MCL) after 4 min Au coating and positioned with its longitudinal direction parallel to the cone generatrix. (b) Resonant frequencies for the MCL prior to coating and the same MCL (now referred to as the CPE-MCL) after 4 min simultaneous Au coating and positioned with its longitudinal direction perpendicular to the cone generatrix. Note that the same value of the ratio ν2 (C-MCL)/νo 2 was measured for CPA-MCL and CPE-MCL. Evidence that the mass deposited on the PA-MCL is identical to that deposited on the PE-MCL is also shown.
