Asymmetrical coplanar waveguide with finite metallization thickness containing anisotropic media

The spectral-domain approach (SDA) is extended to symmetrical and asymmetrical coplanar waveguides with anisotropic media. The quasi-static and hybrid-mode analytical methods are developed in the spectral domain taking the metallization thickness effect into consideration. Numerical computations include the quasi-static and frequency-dependent hybrid-mode values of the phase constants and characteristic impedances for the symmetrical and asymmetrical CPWs and metallization thickness effects in CWPs. Increased metallization thickness significantly reduces the nonreciprocal properties in CPWs with magnetized ferrite and additional dielectric layers.>
