Focal Plane Array-based Millimeter Wave Imaging Radiometer

Integrated Focal Plane Arrays for Millimeter- wave Astronomy

We are developing focal plane arrays of bolometric detectors for sub-millimeter and millimeter-wave astrophysics. We propose a flexible array architecture using arrays of slot antennae coupled via low-loss superconducting Nb transmission line to microstrip filters and antenna-coupled bolometers. By combining imaging and filtering functions with transmission line, we are able to realize unique s...

WSPEC: A waveguide filter-bank focal plane array spectrometer for millimeter wave astronomy and cosmology

Imaging and spectroscopy at (sub-)millimeter wavelengths are key frontiers in astronomy and cosmology. Large area spectral surveys with moderate spectral resolution (R=50-200) will be used to characterize large scale structure and star formation through intensity mapping surveys in emission lines such as the CO rotational transitions. Such surveys will also be used to study the SZ effect, and w...

Dual - Band Millimeter - Wave / Infrared Focal - Plane Arrays

In this paper, a novel arrangement for dual-band millimeter-wave and infrared focal plane array based on slot-antennacoupled metal-oxide-metal diodes is demonstrated. The receiving properties for millimeter-wave and infrared antenna-coupled detector pixels are presented. © 2005 Wiley Periodicals, Inc.

FOCAL POINT AND FOCAL K-PLANE

This paper deals with the basic notions of k-tautimmersions . These notions come from two special cases; that is, tight and taut immersions. Tight and taut based on high and distance functions respectively and their basic notions are normal bundle, endpoint map, focal point, critical normal. We generalize hight and distance functions to cylindrical function and define basic notions of k-taut ...
