Introduction

Nicolas Gregis is a notable inventor based in Fresnes, France. He has made significant contributions to the field of transmission line technology, holding three patents that showcase his innovative methods and techniques.

Latest Patents

One of his latest patents is a method of determining lineal parameters of a transmission line. This method involves determining at least one measurement of the complex propagation factor as a function of frequency, based on measurements taken on the transmission line. It also includes determining the lineal attenuation and phase factor of the transmission line, followed by filtering these measurements using a polynomial frequency regression model that depends on the physical characteristics of the transmission line. Another significant patent is a method for characterizing a section of a transmission line, particularly one that corresponds to a connector or series of connectors. This method injects a reference signal into the line and carries out a time-domain measurement of the reflection of the reference signal. It includes steps for deconvoluting the measurement to generate a sequence of amplitude peaks corresponding to impedance discontinuities, allowing for the deduction of positions and estimates of reflection coefficients.
