About project

Project goal

The aim of the project is to develop a new measurement system enabling precise, broadband determination of the electrical permeability and dielectric losses of liquids used, for example, in immersion cooling of electronics. The developed solution is intended to support the development of modern, energy-efficient cooling technologies for data centers and other electronic systems.

Project description

The proposed project involves the development of a new measurement system for broadband measurement of the dielectric permittivity and dielectric losses of low-loss liquids in the microwave and millimeter-wave frequency ranges as a function of temperature. To the author's knowledge, there is no solution on the market that combines these features, although it should be noted that there are several related solutions with significant limitations. The solution proposed to fill the existing product gap will be based on an open Fabry-Perot resonator coaxially coupled with a network analyzer. The resonator will be placed in a commercially available climatic chamber. Precise knowledge of dielectric properties is of great importance, among other things, for technological progress enabling the reduction of energy and cost consumption in data centers. The proposed approach will utilize the project author's many years of laboratory and commercial experience in resonant material characterization methods, including the use of Fabry-Perot resonators.
Project outcomes

The project will result in the development, implementation, and demonstration of an innovative measurement system for broadband determination of permittivity and dielectric losses of low-loss liquids in the microwave and millimeter wave frequency range. The project will also result in the development of a measurement methodology enabling the characterization of materials over a wide temperature range and the preparation of scientific publications presenting the obtained results. The developed solution is expected to be used in the research and development of cooling fluids for immersion cooling technology in electronics, contributing to the improvement of energy efficiency and reliability of data centers and other electronic systems.
