For many upcoming technical applications in the frequency range of mm waves it is important to know the permittivity of the materials used. Therefore it must be possible to measure them. However, the smaller the wavelength, the greater the cross sens

An open resonator for mm-waves is presented in this paper. It is used for the measurement of the complex permittivity of materials. For the fabrication there must be compromises because the structures are relatively small. During the development of t

In this paper an improved fully canonical waveguide filter which overcomes the major drawback of having a constant attenuation level apart from the passband is presented. By using the principle of resonant hole coupling it becomes possible to assign

The composition of materials generally has an influence on its dielectric properties. Hence it may be possible to determine their composition using microwave dielectric spectra. However with complex materials like foodstuffs it is difficult to devise

In many fields the concept and measurement of quality is of prime importance. The fish industry is no exception to this and many sensory approaches have been devised to quantify this rather intangible property. The EU 5th framework project 'SEQUID' h
