High-temperature superconducting (HTS) materials are becoming more and more attractive in the
context of designing RF microwave filters because of their lower losses and excellent
performance. This book focuses on the superconducting microwave filter and its application in
modern communication. It first presents the basic principles HTS materials and processing and
then introduces several types of multi-band HTS bandpass filter (BPF) discussing their
properties and analyzing equivalent circuit models and their performances. This book is a
valuable resource for students and researchers who are interested in wireless communication and
RF microwave design.
