In diesem Beitrag wird ein neues Verfahren zur Optimierung von Bandpassfiltern aus mehrlagigen frequenzselektiven Schirmen (FSS), die in ein Dielektrikum eingebettet sind, vorgestellt. Das Ziel ist es, die Parameter der gesamten Struktur so zu optimi

A spectral domain approach is presented which allows multiple stacked frequency selective screens (FSS's) to be investigated. The analysis is exact if all arrays have the same periodicity or if a unit cell of finite extent valid for the whole FSS can

We report the results of 1.25-mm observations with the IRAM 30-m telescope of five optically selected QSOs, and five radio-selected QSOs with high redshifts. Five of the QSOs have redshifts greater than 4. One of the radio-quiet, optically selected Q

In this paper a comparison between a rigorous electromagnetic model for transmission through a hexagonal array of circular waveguides in a series of thick, metallic screens and experimental measurements in the far infrared is made. It is found that t

The spectral transmission of inductive metal mesh of grid constant 50.8 μm and of several Fabry-Perot-filters made from the same mesh were measured in the wavenumber range from 50 cm−1 to 250 cm−1. A concise scattering matrix method is used to p

The paper deals with the design and performances of multilayered FSS structures from which the densely packed crossed slots are applied as basic elements for the realization of high-grade band-pass filters in submillimetre wave range to fulfil the sp

We report here the preliminary results of the R&D for a new neutrino mass experiment. This experiment is prepared in the framework of the Microcalorimeters Arrays for a Rhenium Experiment (MARE) project. First tests were made on silicon implanted and

We present a new polarimeter for mm/submm wavelengths. Very low insertion losses and the possibility to tune its operating wavelength in a wide range make it a versatile instrument. It will be used with MPIfR bolometer arrays at different wavelengths

The use of a wobbling secondary mirror to suppress atmospheric noise restricts the scan velocity in mapping modes and has other disadvantages. The fastscanning observing technique allows observations with bolometer arrays from ground based telescopes

With ISO and IRAM we have obtained sensitive infrared and millimetre photometry for a random sample of 17 PG quasars and a sample of 10 pairs of FRII radio galaxies and quasars selected from the 3CR catalogue such that they match in redshift and lobe
