Perfect anomalous reflectors at optical frequencies

Tao He, Tong Liu, Shiyi Xiao +4

Reflecting light to a pre-determined non-specular direction is an important ability of metasurfaces, which is the basis for a wide range of applications (e.g., beam steering/splitt…

Čerenkov radiation in vacuum from a superluminal grating

Daigo Oue, Kun Ding, J. B. Pendry

Nothing can physically travel faster than light in vacuum. This is why it has been considered that there is no Čerenkov radiation (ČR) without an effective refractive index due to…

Tunable terahertz plasmons in graphite thin films

Qiaoxia Xing, Chaoyu Song, Chong Wang +10

Tunable terahertz plasmons are essential for reconfigurable photonics, which have been demonstrated in graphene through gating, though with relatively weak responses. Here, we demo…

Calculating spatiotemporally modulated surfaces: a dynamical differential formalism

Daigo Oue, Kun Ding, J. B. Pendry

Electromagnetic waves in a system with a space and time dependent boundary experience both diffraction and Doppler-like frequency conversion. In order to analyse such situations, c…
