Abstract:

A technique is developed for the design of lenses for transitioning TEM waves between conical andor cylindrical transmission lines, ideally with no reflection or distortion of the waves. These lenses utilize isotropic but inhomogeneous media and are based on a solution of Maxwells equations instead of just geometrical optics. The technique employs the expression of the constitutive parameters, epsilon and mu, plus Maxwells equations, in a general orthogonal curvilinear coordinate system in tensor form, giving what we term as formal quantities. Solving the problem for certain types of formal constitutive parameters, these are transformed to give epsilon and mu as functions of position. Several examples of such lenses are considered in detail. Author
