本文设计并实现了一个可调谐双频无线电能传输耦合谐振器系统。可调谐波段的频率响应可以使用表面贴装变容二极管进行控制。发射器和接收器电路是对称的。顶层包含一个阻抗为50Ω的馈线。通过使用变容二极管，两个相同的半环缺陷接地结构被加载在底部。针对工作在单频段（基于工作频率）的受限无线电能传输系统，提出一种解决方案。研究了几何形状、方向、相对距离和偏移对耦合系数的影响。为验证仿真结果，制作并测试了所提可调谐双频无线电能传输系统。系统面积为40 mm×40 mm。在有效传输距离为22 mm时，在817～1018 MHz调谐频段，以98%的平均耦合效率向接收器输送电能，在1.6GHz固定频段，效率为95%。测量结果与等效模型的模拟结果吻合较好。

The proposal is “mass increases due to strong and gravitational potentials, while it decreases due to Electromagnetic potential”. This proposal explains the big difference in mass between hadrons (protons, neutrons, & mesons) and their components (quarks), mass difference between nucleus and its individual components (protons and neutrons), massless of gamma photons, abnormal masses of mesons and bosons, and the excess in galaxy masses (dark matter). Also, this proposal shows the exact relation between mass and energy: Strong Potential=−3.04mc2| Electric Potential |=−5.57×10−3mc2Gravitational Potential=−1.22×10−7mc2where m represents the excess in mass due to strong potential, or gravitational potential and represents the decrease in mass due to electromagnetic potential. Released energy here equals potential energy and doesn’t equal decrease in mass using the formula E = mc2. Released energy is transferred to heat, photons, kinetic energy… Finally, proposal will try to describe the relation between photon energy and mass of its components using the general equation of kinetic energy: Photon Energy=1/2mc2m is the sum of the individual masses of its components, while the total mass of photon is zero.
