"The first paper in the thesis discussed the development of a complete time-domain THRU-REFLECT-LINE (t-TRL) calibration technique. To validate the error correction technique, two stripline TRL test fixtures are designed and measured by two TDR instruments respectively. The t-TRL calibration is implemented to the recorded TDR/TDT waveforms and the comparison of the magnitude and phase results of S-parameters obtained by t-TRL and VNA TRL shows excellent agreement up to 25GHz.

In the second paper, the application of t-TRL calibration technique to the Root Impulse Energy (RIE) loss calculation is discussed. The RIE loss is theoretically derived for the matched network and the stripline geometry. The sensitivity of the RIE loss with loss tangent is discussed and the Test Coupons are developed for two TRL test fixtures. The RIE loss calculation is based on the impulse response measurement and the impulse response is obtained by implementing the t-TRL calibration technique on time domain TDR/TDT measurements. The RIE losses are calculated for the test vehicles and the applications of RIE loss and Test Coupons on loss tangent determination and substrate material differentiation are showed"--Abstract, page iv.
