A General Waveguide Circuit Theory
This work generalizes and extends the classical circuit theory of electromagnetic waveguides, and definesrices characterizing a linear circuit, and relationships among them, some newly discovered, are derived.

This work presents a complete equivalent-circuit theory for lossy multimode transmission lines that includes new expressions for transmission line impedance matrices, symmetry and lossless conditions, source representations, and the thermal noise of passive multiports.
Design and Performance of Coplanar Waveguide Bandpass Filters
End-coupled resonator bandpass filters built in coplanar waveguide are investigated. The admittance inverter parameters of the coupling gaps between resonant sections are deduced from experiment, and…

A method is illustrated that allows users to estimate the minimum number of stepped mode-stirring samples needed to ensure that the component of uncertainty due to spatial uniformity dominates for a given chamber setup, allowing the use of a simplified expression for uncertainty.

We develop a method to detrend the phases of measured multisine signals. We find a time reference that removes the linear component of the measured phases and aligns them, within a precision…
Calibrated measurement of optoelectronic frequency response
Describes the most straightforward method for accurately measuring the frequency response of optoelectronic devices. The method uses a calibrated optical reference receiver, a modulated optical…
