Advisor: Rhonda Franklin. 1 computer file (PDF); 105 pages.This thesis discusses the characterization of ferromagnetic nanowires (MNWs) and their applications. Chapter 2 introduces the static and dynamic properties of the MNWs and provides an overview to the ferromagnetic resonance (FMR) measurement system. Chapter 3 focuses on the design of the measurement grounded coplanar waveguide (GCPW) circuit, along with the co-simulation of GCPW circuit and ferromagnetic nanowire array (MNWA). Chapter 4 describes the implementation of the VNA-FMR measurement system, including the frequency-sweep and the field-sweep approaches, and the optimization of measurement configurations. The applications of MNWs are demonstrated in two aspects, one in passive microwave device design and another in bio-labeling system design. Chapter 5 presents a MNWA based self-biased circulator at Ka band that has the potential for MMIC integration. Chapter 6 proposes a MNWs-based biolabeling system for multiple cancer cell type detection. An algorithm for multi-MNW type identification is discussed, and the development path from MNWAs to use as MNWs is explained.enbiolabeling systemcirculatorferromagnetic resonancemagnetic nanowirematerial characterizationThesis or Dissertation
