Status report of the CERN light shining through the wall experiment with microwave axions and related aspects
M. Betz, F. Caspers, M. Gasior +1
One way to proof or exclude the existence of axion like particles is a microwave light shining through the wall experiment. In this publication we will emphasize on the engineering…
RF engineering basic concepts: the Smith chart
F. Caspers
The Smith chart is a very valuable and important tool that facilitates interpretation of S-parameter measurements. This paper will give a brief overview on why and more importantly…
RF measurements I: signal receiving techniques
F. Caspers
For the characterization of components, systems and signals in the RF and microwave range, several dedicated instruments are in use. In this paper the fundamentals of the RF-signal…
RF engineering basic concepts: S-parameters
F. Caspers
The concept of describing RF circuits in terms of waves is discussed and the S-matrix and related matrices are defined. The signal flow graph (SFG) is introduced as a graphical mea…
