论文摘要
在这项研究中，我们揭示了在存在蠕动介电常数调节的情况下表面之间的非接触式摩擦力。我们的设置包括导电介质，气隙和介电底物，在该基材上我们具有发射电磁辐射的时空调节光栅。辐射从光栅接收能量和动力，最终被导电介质吸收或从介电侧的光栅传播，从而导致电磁功率损失和表面的侧向力。
In this study, we reveal noncontact frictional forces between surfaces in the presence of peristaltic permittivity modulation. Our setup comprises a conducting medium, an air gap, and a dielectric substrate on which we have a space-time-modulated grating that emits electromagnetic radiation. The radiation receives energy and momentum from the grating, which is eventually absorbed by the conducting medium or propagates away from the grating on the dielectric side, resulting in electromagnetic power loss and lateral forces at the surfaces.
