20.500.12556/RUL-143985 Antenna-coupled titanium microbolometers application for precise control of radiation patterns in terahertz time-domain systems An ability of lensless titanium-based antenna coupled microbolometers (Ti-µbolometers) operating at room temperature to monitor precisely radiation patterns in terahertz time-domain spectroscopy (THz-TDS) systems are demonstrated. To provide comprehensive picture, two different THz-TDS systems and Ti-µbolometers coupled with three different antennas—narrowband dipole antennas for 0.3 THz, 0.7 THz and a log-periodic antenna for wideband detection—were selected for experiments. Radiation patterns, spatial beam profiles and explicit beam evolution along the propagation axis are investigated; polarization-sensitive properties under various THz emitter power ranges are revealed. It was found that the studied Ti-µbolometers are convenient lensless sensors suitable to discriminate and control THz radiation pattern features in various wideband THz-TDS systems. titanium-based microbolometeric sensors THz time-domain spectroscopy systems precise THz mode control radiation pattern monitoring mikrobolometrični senzorji na osnovi titana THz sistemi spektroskopije v časovni domeni natančna kontrola THz načina spremljanje vzorcev sevanja true false true Angleški jezik Slovenski jezik Članek v reviji 2023-01-25 10:14:53 2023-01-25 10:14:54 2023-01-27 03:35:39 0000-00-00 00:00:00 2021 0 0 11 str. iss. 10, art. 3510 Vol. 21 May 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.3 1424-8220 10.3390/s21103510 139338243 sensors-21-03510-v2.pdf sensors-21-03510-v2.pdf 1 44518FFD24A2F42D3B84EA7804689313 66268d3fb5d19cac7173ae5625db3d7d8d8f1fbd10824a97a7ad01ddcf2e4744 7559a646-9c91-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=166082 https://www.mdpi.com/1424-8220/21/10/3510 1 790e292b-9c90-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=166080 Fakulteta za elektrotehniko 0 0 0
