Dielectric characterization of materials

Dielectric material properties are needed as input for optimized package design of RF systems like 5G. The expert session will give an insight into different aspects of the dielectric properties, their impacts and how they are extracted. This online session series aims to address our customers, partners and interested parties from industry, politics and science. Participation is free of charge, registration is required.

Speaker: Oliver Schwanitz

The characterization of electrical properties of materials (permittivity & loss factor) plays a key role in the design of entire RF packages and their corresponding interconnects in the entire system. While the determination of these parameters in the range below 1 GHz is still relatively easy using capacitive probes, the extraction of these parameters for the range 5G and higher poses a particular challenge. In this range, the electric field is no longer decoupled from the magnetic field due to the frequency and thus an electromagnetic wave is present, so other methods are required. One is e.g. a cavity resonator for the frequency range of 10 GHz - 26 GHz or a quasi-optical bank for the characterization of the range of 40 GHz - 170 GHz. In addition to the extraction process of the parameters, the materials change their electrical properties over time due to environmental influences such as temperature and humidity, which can lead to entire system failure. It is therefore necessary to know these effects from the beginning of the package design.

Search / advanced search of the idw archives
Combination of search terms

You can combine search terms with and, or and/or not, e.g. Philo not logy.


You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).


Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.

Selection criteria

You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).

If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
