| Abstract: | We study the guided propagation of whistler waves along cylindrical ducts with enhanced density in a collisional magnetoplasma.
It is shown that under certain conditions, the presence of comparatively small dissipative losses due to electron collisions
in a plasma medium can lead to significant changes in the dispersion characteristics and field structures of whistler modes
guided by such ducts compared with the case of a collisionless plasma. We present the results of numerical calculations showing
such changes in the properties of whistler modes.
