Resonators
The family of dielectric resonators for precise measurements of electromagnetic properties of materials
at microwave frequencies
at microwave frequencies
QWED manufactures several types of resonators (also referred to as test fixtures) for precise measurements of electromagnetic properties of materials at microwave frequencies. Each resonator is equipped with specialised software for extracting the relevant data (typically, complex permittivity or real permittivity and loss tangent) from measurements. The resonators and the accompanying software are based on years of research led by QWED’s expert Prof. Jerzy Krupka and documented in dozens of worldwide-appreciated scientific and technical publications. The quality of the resonators has been recognised by industrial practitioners, leading researchers, and industrial standard creators. QWED is especially proud of recognition by Agilent Technologies... read more
Split post dielectric resonators (SPDR)
SPDRs can be used for measurements of laminar dielectric materials and LTCC substrates at frequencies from 1 GHz to 20 GHz.

Single post dielectric resonators (SiPDR)
SiPDRs are designed for measurements of surface resistivity (or effective conductivity) of conductors and superconductors from 2 GHz to 30 GHz. SiPDRs may also be applied to measurements of surface resistivity of susceptors, which are commonly used to enhance local power dissipation in microwave heating. Susceptors are often referred to as elements of "active packaging" of foods designed for domestic microwave ovens

One of the single dielectric resonators
TE01δ mode dielectric resonator
TE01δ mode dielectric resonators are designed for very precise measurements of permittivity and dielectric loss tangent of low loss dielectrics in frequency band from 1 GHz to 20 GHz. Unlike the SPDRs, they can be applied to powdered, granulated or liquid materials.

Award Certificate for Prof. Jerzy Krupka for the invention of Resonators for Precise Measurements of Electromagnetic Properties of Materials at Microwave Frequencies
QWED offers standard reference materials for dielectric measurements. For example, samples of single crystal quartz can be ordered by interested customers, either in conjunction with a resonator purchase or independently.
