Absorption enhancement and total absorption in a graphene-waveguide hybrid structure AIP Advances 7, 025101 (2017); https://doi.org/10.1063/1.4975706The influence of the edge effect on the skyrmion generation in a magnetic nanotrack AIP Advances 7, 025105 (2017) A thermally tunable slot-coupled dielectric resonator antenna (DRA) has been designed and prepared by placing a thermosensitive ceramic resonator onto the slot. Typical magnetic resonance occurs in the resonator, which is closely related to its dielectric constant. Because the dielectric constant of the ceramic resonator decreases as the temperature increases, the resonance frequency of the proposed DRA increases as the temperature increases. The simulated results are in good agreement with the measured ones, which confirms the thermally tunable behavior. This approach provides a way for designing the frequency tunable antennas. © 2017 Author(s).

Design and analysis of nickel ferrite resonator antenna for C band applications

“…One promising application in resonator research field is DRA 8 or ferrimagnetic resonator antenna (FRA) 9,10 . The ferrimagnetic materials application as FRA is interesting due its lower conductivity than conducting materials, which reduces the heating losses, 11 and presents the tuning possibility 12 . Different synthesis techniques, and modification in process variables, are applied to modify electrical and magnetic characteristics of materials 13 …”
