In this paper, the possibility of exploiting carbon nanotubes as X-ray waveguides is explored through analytical and numerical solutions of Maxwell's equations. It is shown that nanotubes coated with various materials can theoretically sustain electromagnetic modes. The factors determining the modes

โฆ Synopsis
We study the propagation of X-rays in very narrow slits or waveguides. The onset of waveguiding effects is estimated analytically and quantified by finite-difference field calculations. A critical thickness is given below which waveguiding effects have to be taken into account. Finally, we consider the transmission of the smallest possible slits i.e. planar single-mode waveguides.

The fine features of X-ray propagation both in an ultra-narrow collimator and at glancing reflection from a smooth surface can be described within the unified theory of trapped radiation propagation: surface channeling in l-guides and bulk channeling in submicron/ nano-guides.
