A pulsed millimeter-wave network analyzer operating in the 40-60 GHz band has been developed at Georgia Tech. The network analyzer consists of three custom-built units 1 a MMW six-port system that includes sensitive superheterodyne receivers, 2 a phaselocked MMW frequency synthesizer, and 3 a microprocessor-based system controller that provides internal control functions and communication interfaces. An IBM-PC desktop computer is used to input instructions, collect data, and perform required computations. This report summarizes the design, development, and operation of the network analyzer and discusses algorithms used for 1 calibration of the six-port system, 2 complex reflection coefficient computations, and 3 tissue dielectric property computations. Keywords Bioeffects Millimeter wave Pulsedcontinuous wave and Permittivity measurement.
