Abstract:

Compact closed-form mathematical expressions for the propagation parameters (characteristic impedance,
effective permittivity and attenuation) of coplanar waveguides (CPW) are presented. The
formulas take into account asymmetric structures, thick electrodes and two-layered substrates, and
thus are perfectly tailored for the optimization of electro-optical modulators. Excellent agreements,
within a range of frequencies up to 100 GHz, are found with full-wave finite elements results from
commercial software (HFSS) and with measures reported in the literature, for material and geometrical
CPW parameters of practical relevance for the design of electro-optical modulators |
