1. 1. Growth and Phase Stability of Titanium Aluminum Nitride Deposited by High Power Impulse Magnetron Sputtering

   Master-uppsats, Plasma och beläggningsfysik

   Författare :Chung-Chuan Lai; [2011]
   Nyckelord :HiPIMS; co-sputtering; diffusion; microstructure; spinodal decomposition; Ti1-xAlxN;

   Sammanfattning : In this work, we investigate the relation between the diffusion behavior of Ti1-xAlxN at elevated temperatures and the microstructure. Thinfilm samples are synthesized by reactive co-sputtering with two cathodes. LÄS MER

3. 2. Use SNA instead of VNA to characterize indoor channel : implementing and rms theory

   Kandidat-uppsats, Avdelningen för elektronik, matematik och naturvetenskap

   Författare :Jingou Lai; Che Liu; [2010]
   Nyckelord :network analyzer; rms delay; hilbert transform;

   Sammanfattning : In this report we focus on the use of an economical way on how Scalar Network Analyzer (SNA) works instead of Vector Network Analyzer (VNA) to estimate the phase angle of signals in indoor channel. This is detailed in RMS delay theory and simulation section, experimental is designed in the according Experiment Design section, where we also state the required measurements known from the math part.
