Design of ALPHA Phase I: A Plasma Haloscope for 10--20 GHz Post-Inflation Axions
ALPHA Collaboration, Xiran Bai, Rustam Balafendiev +54
The axion is a well-motivated hypothetical particle capable of resolving both the strong CP problem and the dark matter mystery, with recent post-inflationary cosmological simulati…
Tuning Plasma Frequency of Nested Wire Media
Denis Sakhno, Pavel A. Belov
We study nested wire media possessing and rotational symmetries whose plasma frequencies can be controlled through breathing deformation. Numerical simulations reveal t…
Single-shot near-field reconstruction of metamaterial dispersion
Eugene Koreshin, Denis Sakhno, Jim A. Enriquez +1
We present a single-shot near-field technique, where the near-field scan is performed on a single sample without repeating measurements or averaging over multiple samples, to recon…
Volume-Preserving Deformation of Honeycomb Wire Media Enables Broad Plasma Frequency Tunability
Denis Sakhno, Jim A. Enriquez, Pavel A. Belov
We demonstrate significant tunability of the plasma frequency in a wire medium by mechanically deforming a lattice of parallel metallic wires arranged at the nodes of a honeycomb s…
Plasma Frequency of Wire Medium Revisited
Denis Sakhno, Pavel A. Belov
This paper revisits a model for the plasma frequency of a simple wire medium formed by a rectangular lattice of parallel metallic wires. We provide a comparative analysis of existi…
