  物电论坛754期特别邀请英国南安普顿大学光电研究中心中级研究员Jun-Yu (Bruce) Ou博士主讲,具体安排如下:

  一、主 题:Controlling light with nano mechanical photonic metamaterials

  二、主讲人:Jun-Yu (Bruce) Ou 博士 (英国南安普顿大学)

  三、时 间:2017年10月18日(周三)9:30

  四、地 点:电子科大沙河校区逸夫楼521室

  五、主持人:丁霄 付教授

  六、内容简介:

  Metamaterials are artificial media with all sorts of unusual functionalities achieved by structuring on a length scale smaller than that of the external stimulus. In optics, the development of metamaterials has led to demonstrations of fascinating optical properties such as negative refraction, invisibility, perfect lenses and many more. Nevertheless, few of these demonstrations have led to practical applications, largely due to the unique properties of metamaterials are narrowband. Here we develop nanomechanically reconfigurable metamaterials that offer a flexible platform for static and dynamic control of metamaterial optical properties. Exploiting this, we use electrostatic, Lorentz and near field optical forces to drive high-contrast, high-speed active tuning, modulation and switching of metamaterial properties.
