18 Mar 2022 | | Abstract: | In this work we study electromagnetic properties of a resonator recently
suggested for the search of axions - a hypothetical candidate to explain dark
matter. A wire medium loaded resonator (called a plasma haloscope when used to
search for dark matter) consists of a box filled with a dense array of parallel
wires electrically connected to top and bottom walls. We show that the
homogenization model of wire medium works for this resonator without mesoscopic
corrections, and that the resonator quality $Q$ at the frequency of our
interest drops versus the growth of the resonator volume $V$ until it is
dominated by resistive losses in the wires. We find that even at room
temperature metals like copper can give quality factors in the thousands, an
order of magnitude higher than originally assumed. Our theoretical results for
both loaded and unloaded resonator quality factors were confirmed by building
an experimental prototype. We discuss ways to further improve WM loaded
resonators. | | Source: | arXiv, 2203.10083 | | Services: | Forum | Review | PDF | Favorites | |
