Abstract :
The pole and zero matching method has been applied for the dispersion analysis of waveguides loaded with metamaterial surfaces. Very good agreement with commercial software packages has been observed. This allows to produce a synthesis procedure, where the admittance characteristics of the metasurface are designed to meet the dispersion requirements. A matched finite structure has been designed and fabricated. Preliminary experimental results suggest successful matching of the structure.
