Tuning of Strong Nonlinearity in rf SQUID Meta-Atoms
Ethan Zack, Daimeng Zhang, Melissa Trepanier +5
Strong nonlinearity of a self-resonant radio frequency superconducting quantum interference device (rf-SQUID) meta-atom is explored via intermodulation (IM) measurements. Previous…
Tunable Superconducting Josephson Dielectric Metamaterial
Melissa Trepanier, Daimeng Zhang, Lyudmila Filippenko +2
We demonstrate a low-dissipation dielectric metamaterial with tunable properties based on the Josephson effect. Superconducting wires loaded with regularly spaced Josephson junctio…
Coherent Oscillations of Driven rf SQUID Metamaterials
Melissa Trepanier, Daimeng Zhang, Oleg Mukhanov +7
Through experiments and numerical simulations we explore the behavior of rf SQUID (radio frequency superconducting quantum interference device) metamaterials, which show extreme tu…
Intermodulation in Nonlinear SQUID Metamaterials: Experiment and Theory
Daimeng Zhang, Melissa Trepanier, Thomas Antonsen +2
The response of nonlinear metamaterials and superconducting electronics to two-tone excitation is critical for understanding their use as low-noise amplifiers and tunable filters.…
Tunable Broadband Transparency of Macroscopic Quantum Superconducting Metamaterials
Daimeng Zhang, Melissa Trepanier, Oleg Mukhanov +1
Narrow-band invisibility in an otherwise opaque medium has been achieved by electromagnetically induced transparency (EIT) in atomic systems. The quantum EIT behaviour can be class…
Realization and modeling of rf superconducting quantum interference device metamaterials
M. Trepanier, Daimeng Zhang, Oleg Mukhanov +1
We have prepared meta-atoms based on radio frequency superconducting quantum interference devices (RF SQUIDs) and examined their tunability with dc magnetic field, rf current, and…
Column collapse of granular rods
M. Trepanier, Scott V. Franklin
We find the collapse of columns of granular rods to show range of behaviors that depends on particle aspect ratio (length to diameter ) and initial pile geometry (height/rad…
