Flux Density through Guides with Microstructured Twisted Clad DB Medium.

The paper deals with the study of flux density through a newly proposed twisted clad guide containing DB medium. The inner core and the outer clad sections are usual dielectrics, and the introduced twisted windings at the core-clad interface are treated under DB boundary conditions.The pitch angle of twist is supposed to greatly contribute towards the control over the dispersion characteristics of the guide.The eigenvalue equation for the guiding structure is deduced, and the analytical investigations aremade to explore the propagation patterns of flux densities corresponding to the sustained low-order hybrid modes under the situation of varying pitch angles. The emphasis has been put on the effects due to the DB twisted pitch on the propagation of energy flux density through the guide. [ABSTRACT FROM AUTHOR]
