In this paper, two THz reflectarray surfaces have been designed and fabricated in order to deflect a plane wave with any polarization and with a specific incident angle to three different specific directions each at distinct three frequencies of 0.7,

Faraday rotation is a fundamental property present in all nonreciprocal optical elements. In the THz range, graphene displays strong Faraday rotation; unfortunately, it is limited to frequencies below the cyclotron resonance. Here, we show experiment

To address the need for large area dry graphene transfer techniques in Nanomechanical applications we use transfer printing to suspend large areas of graphene on pre-patterned substrates with cavities. We find that using this method, clean suspended

We report a thorough investigation of the electrically-induced metal-insulator transition in vanadium dioxide (VO 2 ) for abrupt switching in 2-terminal devices (0.24 mV/dec at 25 °C, 0.38 mV/dec at 50 °C). We exploit the electrothermal actuation m
