DIRECT EVALUATION OF COMPLEX PERMITTIVITY FROM TRANSMISSION LINE DISCONTINUITY MEASUREMENTS Jawad Abdulnour1, Louis Marchildon2, Cevdet Akyell,'and Ke WUl. ABSTRACT Anew way to determine the complex permittivity of liquid or solid dielectric material samples is proposed. The method makes use of a discontinuity in a rectangular waveguide. The discontinuity is either a rectangular post or a cylinde
