在这项工作中，我们报告了设计用于射频电路的高Q球面振荡器的机电研究。利用激光测振仪对由硅芯和厚纳米金刚石壳组成的共振复合球进行了研究，以获得系统的机械品质因数，并识别系统的共振频率和本征模式。利用有限元模拟对实验数据进行了分析和验证。此外，还在电容耦合球体上进行了反射/透射率测量，以评估系统的电参数。这些研究的主要目的是评估钻石基球形谐振器用于现代通信设备的潜力。
In this work, we report on the electro-mechanical studies of high-Q spherical oscillators designed to operate in radio-frequency circuits. Resonating composite spheres, consisting of a silicon core and a thick nanodiamond shell, were studied by laser vibrometry in order to obtain mechanical quality factors and identify the resonant frequencies and eigenmodes of the system. Finite element method simulations were used to analyze and confirm the experimental data. Additionally, reflection/transmission measurements were carried out on capacitively coupled spheres in order to evaluate the electrical parameters of the system. The main aim of these investigations was to evaluate the potential of diamond-based spherical resonators to be used in modern communication devices.
