Спектральный Отклик Матриц Полуволновых И Электрически Малых Антенн С Синис-Болометрами

Abstract

Two types arrays of ring half – wave and electrically small antennas (the typical sizes of the elements correspond to 1/10 of the wavelength) of SubTHz band with integrated Superconductor – Insulator – Normal metal – Insulator-Superconductor (SINIS) bolometers have been developed, fabricated and investigated. It is necessary to make numerical modeling of the full structure and to use additional reference channels in experimental studies for improving the accuracy of the spectral response estimations of receiving arrays. In this work, three reference channels were used for normalization: a pyroelectric receiver outside the cryostat and two cold channels – a RuO2 bolometer and chain of NIS junctions as a thermometer.
