A High Return Loss of Microwave Bandpass Filter Using Superconducting Electrospun YBCO Nanostructures

A high return loss (-30 dB), small size (100 mm2) and broad bandwidth (1.5 GHz) microwave bandpass filter has been designed using finite element modelling and developed using the superconducting YBa2Cu3O7-δ (YBCO) thin films deposited on a (10 × 10 mm2) LaAlO3 substrate by spin coating. The thin fil...
