For this purpose, the effects of carbon nanotube’s inner and outer tubes’ material property parameters (?, ?) on electromagnetic wave propagation are discussed. The effects of interaction between the carbon nanotube’s inner and outer tubes on the electromagnetic wave propagation are defined. Nonlocal effects of the DWCNT on electromagnetic wave propagation are examined. Besides, the electromagnetic wave propagation frequencies are specifically investigated, taking the DWCNT’s nonlocal effects and material property parameters (?, ?) into account. When the wavenumber, k, is greater than 1.8 × 1010, the frequencies of the fundamental mode and the second mode converge to 3.554 × 108 Hz. Additionally, the electromagnetic wave propagation frequencies decrease with the increase of the DWCNT’s nonlocal parameter (?) and decrease with material parameter (D). © 2021 by the authors.en10.3390/ma14154069info:eu-repo/semantics/openAccessCarbon nanotubesDouble-walled carbon nanotubesElectromagnetic wave propagationMaxwell equationsCircular waveguidesElectromagnetic wave propagationMagnetic materialsNanotubesDouble walled carbon nanotubesFundamental modesMaterial parameterMaterial property parametersNon-local effectNonlocalWave numbersMultiwalled carbon nanotubes (MWCN)Article1415Q1WOS:0006820807000012-s2.0-85111378370Q2
