- Abstract
A new structure is proposed for microwave impedance matching in a desired frequency range. This structure utilizes a waveguide filled by a longitudinally inhomogeneous dielectric. The electric permittivity function of the structure is expanded in a truncated Fourier series first. Then, the optimum values of the coefficients of the series are obtained through an optimization approach. The usefulness of the proposed structure is verified using a comprehensive example. © 2008 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2009.
