Scattering Cancellation based Cloaking for the Maxwell-Cattaneo Heat Waves
M. Farhat, S. Guenneau, P. -Y. Chen +2
In this work we theoretically propose scattering cancellation-based cloaks for heat waves that obey the Maxwell-Cattaneo equation. The proposed cloaks possess carefully tailored di…
Generalized Parity-Time Symmetry Condition for Enhanced Sensor Telemetry
Pai-Yen Chen, Maryam Sakhdari, Mehdi Hajizadegan +4
Wireless sensors based on micro-machined tunable resonators are important in a variety of applications, ranging from medical diagnosis to industrial and environmental monitoring.Th…
Tunable Terahertz Amplification Based on Photoexcited Active Graphene Hyperbolic Metamaterials
Tianjing Guo, Liang Zhu, Pai-Yen Chen +1
The efficient amplification and lasing of electromagnetic radiation at terahertz (THz) frequencies is a non-trivial task achieved mainly by quantum cascade laser configurations wit…
Thermally Oxidized Two-dimensional TaS2 as a High-\k{appa} Gate Dielectric for MoS2 Field-Effect Transistors
Bhim Chamlagain, Qingsong Cui, Sagar Paudel +3
We report a new approach to integrating high-\k{appa} dielectrics in both bottom- and top-gated MoS2 field-effect transistors (FETs) through thermal oxidation and mechanical assemb…
