Spectral properties of materials and devices based on magnetic nanoparticles for THz optics
- 1. Natsional'nyj Issledovatel'skij Tomskij Gosudarstvennyj Univ., Tomsk (Russian Federation)
Description
Samples of devices for amplitude modulation of radiation in the THz range of the spectrum are considered. Prototypes of two types of devices based on magnetic nano- and microparticles of a soft magnetic alloy have been created. The first type was created on the basis of polymer composite films consisting of fluoroplast and magnetic particles oriented in the presence of a constant magnetic field. The second type was created on the basis of dispersions of magnetic particles in viscous oil placed between pairs of Helmholtz coils which make it possible to create an oriented magnetic field. The obtained prototypes make it possible to attenuate THz radiation in the entire range under study (0.4–1.8 THz), depending on the mutual orientation of nanoparticles in the medium, the direction and polarization of the beam. The properties of devices of the second type in the THz range can be controlled in real time by changing the orientation of nanoparticles by magnetic field
Abstract (Russian)
Рассматриваются образцы устройств амплитудной модуляции излучения в ТГц диапазоне спектра. Созданы прототипы двух типов устройств на основе магнитных нано- и микрочастиц магнитомягкого сплава. Первый тип создан на основе полимерных композитных плёнок, состоящих из фторопласта и магнитных частиц, ориентированных в присутствие постоянного магнитного поля. Второй тип создан на основе дисперсий магнитных частиц в вязком масле, помещённых между парами катушек Гельмгольца, позволяющих создавать ориентированное магнитное поле. Полученные прототипы позволяют ослаблять ТГц излучение во всем исследуемом диапазоне (0.4–1.8 ТГц) в зависимости от взаимной ориентации наночастиц в среде, направления и поляризации пучка. Cвойствами устройств второго типа в ТГц диапазоне можно управлять в реальном времени, изменяя ориентацию наночастиц магнитным полемAdditional details
