Abstract : Research concerned a fundamental theoretical study of open-structural guiding and radiating systems with emphasis on varying degrees of gen eralization of mode-type and media properties, and a study, in detail, of specific novel open structures showing some promise of utility. The reformulation is given of Maxwell's equations and their solution for the broadest generalization possible as regards medium properties and geo metrical cross section in which the only restric tion is that of linearity. A method of treat ing guiding open cylindrical systems numerically is outlined and is applied to the case of a ra dial inhomogeneity. A study is presented di rected toward a complete analysis and catalog ing of all classes of high frequency guided waves (infinite ion mass) on an open magneto plasma column with density inhomogeneity treated by a perturbation technique. The V-line struc ture is discussed. The V-line is a voltage tun able radiating element using a ferroelectric of modest tuneability as a binding medium. Research carried out on a class of low loss, low permit tivity ferroelectric materials is also presented. (Author)
