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…
Designing Topological Defect Lines Protected by Gauge-dependent Symmetry Indicators
Erda Wen, Dia'aaldin J. Bisharat, Robert J. Davis +2
Symmetry indicators are a modern tool for characterizing topological phases that require only minimal computational expense but provide an elegant means of designing practical devi…
Power-dependent Reflective Metasurface with Self-induced Bandgap
Xiaozhen Yang, Erda Wen, Daniel F. Sievenpiper
A metallic ring based, diode-integrated, low-profile, power-dependent, reflective metasurface working from 3 GHz to 3.6 GHz is proposed in this letter. Unlike the previous study wh…
Broadband time-modulated absorber beyond the Bode-Fano limit by energy trapping
Xiaozhen Yang, Erda Wen, Daniel F. Sievenpiper
Wide-band absorption is a popular topic in microwave engineering to protect sensitive devices against broadband sources. However, the Bode-Fano criterion defines the trade-off betw…
