The microwave properties of YBCO photonic crystal structure microstrip

We have fabricated three YBCO microstrip lines. One is conventional microstrip line. Two are etched periodic holes. The thickness for the microstrip lines with and without holes are 0.3 and 0.451-1m, respectively. The periodic holes in the microstrip line change the microwave properties more signifi...

Description
Summary:We have fabricated three YBCO microstrip lines. One is conventional microstrip line. Two are etched periodic holes. The thickness for the microstrip lines with and without holes are 0.3 and 0.451-1m, respectively. The periodic holes in the microstrip line change the microwave properties more significantly in the case of thin film than thick film. We have also fabricated YBCO photonic bandgap (PBG) microstrip circular disk filter in film with thickness 0.7 urn. The center frequency of the pass hand filter is 12.23 GHz. The filter provides band width 1.6% and low insertion loss about -0.5 dB.
