Design of ALPHA Phase I: A Plasma Haloscope for 10--20 GHz Post-Inflation Axions
ALPHA Collaboration, Xiran Bai, Rustam Balafendiev +53
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…
Anisotropy in a wire medium resulting from the rectangularity of a unit cell
Denis Sakhno, Rustam Balafendiev, Pavel A. Belov
The study is focused on the dispersion properties of a wire medium formed by a rectangular lattice of parallel wires at the frequencies close to its plasma frequency. While the eff…
Controlling the dispersion of longitudinal waves via the affine deformation of the interlaced wire medium
Denis Sakhno, Eugene Koreshin, Pavel A. Belov
We studied the dispersion properties of double interlaced wire metamaterials with geometry modified by affine transformation. That metamaterials were found to support eigenmodes wi…
Effective Medium Perspective on Topological Transitions in Metamaterials
Leon Shaposhnikov, Denis Sakhno, Daniel A. Bobylev +1
Many properties of photonic structures rely on band topology characterized by the integer invariants that can change during the topological transitions and give rise to the disorde…
Quadraxial metamaterial
Denis Sakhno, Eugene Koreshin, Pavel A. Belov
We study the dispersion of electromagnetic waves in a spatially dispersive metamaterial with Lorentz-like dependence of principal permittivity tensor components on the respective c…
Longitudinal electromagnetic waves with extremely short wavelength
Denis Sakhno, Eugene Koreshin, Pavel A. Belov
Electromagnetic waves in vacuum and most materials have transverse polarization. Longitudinal electromagnetic waves with electric field parallel to wave vector are very rare and ap…
