Ultra-wideband Antireflection Assisted by Continuously Varying Temporal Medium
Yi Zhang, Liang Peng, Zhengjie Huang +2
We demonstrate that reflectionless propagation of electromagnetic waves between two different materials can be achieved by designing an intermediate temporal medium, which can work…
A 60-GHz Radar Sensor for Micron-Scale Motion Detection
Marcel Balle, Chengkai Zhu, Bin Zhang +2
A compact, continuous-wave, mmWave radar sensor is developed for non-contact detection of micron-scale motions. This board-integrated radar system consists of a pair of mmWave tran…
Time-Domain Doppler Biomotion Detections Immune to Unavoidable DC Offsets
Qinyi Lv, Lingtong Min, Congqi Cao +7
In the past decades, continuous Doppler radar sensor-based bio-signal detections have attracted many research interests. A typical example is the Doppler heartbeat detection. While…
An Invisible Metallic Mesh
Dexin Ye, Ling Lu, John D. Joannopoulos +2
We introduce a solid material that is itself invisible, possessing identical electromagnetic properties as air (i.e. not a cloak) at a desired frequency. Such a material could prov…
Experimental observation of Weyl points
Ling Lu, Zhiyu Wang, Dexin Ye +4
In 1929, Hermann Weyl derived the massless solutions from the Dirac equation - the relativistic wave equation for electrons. Neutrinos were thought, for decades, to be Weyl fermion…
Achieving Anisotropy in Metamaterials made of Dielectric Cylindrical Rods
Liang Peng, Lixin Ran, Niels Asger Mortensen
We show that anisotropic negative effective dispersion relation can be achieved in pure dielectric rod-type metamaterials by turning from the symmetry of a square lattice to that o…
