THz-driven split ring resonator undulator

open access: yesPhysical Review Accelerators and Beams, 2021
We propose a short period undulator based on the electromagnetic field pattern in a THz-driven split ring resonator structure. An analytical model is developed that allows us to assess the key performance parameters of the undulator and to estimate the ...

Wearable Ring Resonator Antenna [PDF]

open access: yesphysica status solidi (a), 2018
In this paper a metamaterial wearable antenna is proposed. The proposed design is based on a transmission line coupled to a pair of double ring resonators (DRRs) on an e‐textile substrate. The metallic antenna layer is fully embroidered providing both electromagnetic and mechanical good properties.

Dynamically tunable terahertz metamaterial sensor based on metal–graphene hybrid structural unit

open access: yesAIP Advances, 2022
By verifying the electromagnetic response characteristics of graphene in the low terahertz (THz) band, a terahertz metamaterial sensor is proposed. The unit cell of the metamaterial sensor is a split ring resonator nested square ring resonator. The split

Topological resonances in a Möbius ring resonator

open access: yesCommunications Physics, 2023
AbstractA Möbius strip, fascinating for its unique topological property of being a one-side nonorientable surface, has inspired mathematicians, physicists, engineers, and artists for many centuries. In a coherent system, coherent waves on the nonorientable surfaces reveal rich topological dynamics due to the interplay of coherence and topology. Here we
