Nanoscale Electrodynamic Response of Nb Superconductors
Tamin Tai, Behnood G. Ghamsari, Steven M. Anlage
Our objective is to study the extreme and local electrodynamic properties of Niobium (Nb), and to relate these properties to specific defects that limit the ultimate RF performance…
High-Temperature Superconducting Multi-Band Radio-Frequency Metamaterial Atoms
Behnood G. Ghamsari, John Abrahams, Steven M. Anlage
We report development and measurement of a micro-fabricated compact high-temperature superconducting (HTS) metamaterial atom operating at a frequency as low as 53MHz. The de…
Determination of the Optical Index for Few-Layer Graphene by Reflectivity Spectroscopy
Behnood G. Ghamsari, Jacob Tosado, Mahito Yamamoto +2
We have experimentally studied the optical refractive index of few-layer graphene through reflection spectroscopy at visible wavelengths. A laser scanning microscope (LSM) with a c…
Imaging the Anisotropic Nonlinear Meissner Effect in Nodal YBaCuO Thin-Film Superconductors
Alexander P. Zhuravel, B. G. Ghamsari, C. Kurter +6
We have directly imaged the anisotropic nonlinear Meissner effect in an unconventional superconductor through the nonlinear electrodynamic response of both (bulk) gap nodes and (su…
Mgb2 Nonlinear Properties Investigated under Localized High RF Magnetic Field Excitation
Tamin Tai, Behnood G. Ghamsari, Steven M. Anlage +2
In order to increase the accelerating gradient of Superconducting Radio Frequency (SRF) cavities, Magnesium Diboride (MgB2) opens up hope because of its high transition temperature…
