Helical Phononic Modes Induced by a Screw Dislocation
Yun Zhou, Robert Davis, Li Chen +3
In this study, we investigate a one-dimensional (1D) unidirectional phononic waveguide embedded within a three-dimensional (3D) hexagonal close-packed phononic crystal, achieved by…
Multifunctional Metasurface: Simultaneous Beam Steering, Polarization Conversion and Phase Offset
Xiaozhen Yang, Erda Wen, Dinesh Bharadia +1
A varactor-based reconfigurable multifunctional metasurface capable of simultaneous beam steering, polarization conversion and phase offset is proposed in this paper. The unit cell…
Real-data-driven Real-time Reconfigurable Microwave Reflective Surface
Erda Wen, Xiaozhen Yang, Daniel F. Sievenpiper
Manipulating the electromagnetic (EM) reflection behavior from an arbitrary surface dynamically on arbitrary design goals is an ultimate ambition for many EM stealth and communicat…
All-passive Microwave-Diode Nonreciprocal Metasurface
Xiaozhen Yang, Erda Wen, Daniel F. Sievenpiper
Breaking reciprocity in the microwave frequency range will have important implications for modern electronic systems. Since it usually involves bulky biasing magnets or complex spa…
