Design, fabrication and application of a dedicated thick-film hybrid time domain reflectometer
This work presents a design process for developing a dedicated hybrid
thick-film time domain reflectometer. The design process allows for variation of the
pulse generator characteristics as well as the output impedance of the unit.
The unit is fabricated using standard thick-film hybrid techniques while giving
consideration to problems encountered at microwave frequencies. This thesis also
presents an overview of time domain reflectometry and its applications. Special
emphasis is given to the problem of characterizing material dielectric constants using
