Optimum excitation wavelength and photon energy threshold for spintronic terahertz emission from Fe/Pt bilayer

iScience, 2022
Summary: Terahertz emission from ferromagnetic/non-magnetic spintronic heterostructures had been demonstrated as pump wavelength-independent. We report, however, the pump wavelength dependence of terahertz emission from an optimized Fe/Pt spintronic ...

Formation of porous clay ceramic using sago waste ash as a prospective additive material with controllable milling [PDF]

Science of Sintering, 2014
A novel type of ceramic material was produced by mixing sago waste ash from the sago processing industry in Indonesia with clay. The composition was prepared by adding 50 %wt amount of sago waste into the clay, then a series of samples was ...

The Far‐infrared Earth [PDF]

Reviews of Geophysics, 2008
The paper presents a review of the far‐infrared (FIR) properties of the Earth's atmosphere and their role in climate. These properties have been relatively poorly understood, and it is one of the purposes of this review to demonstrate that in recent years we have made great strides in improving this understanding.

Machine learning for pattern and waveform recognitions in terahertz image data

Scientific Reports, 2021
Several machine learning (ML) techniques were tested for the feasibility of performing automated pattern and waveform recognitions of terahertz time-domain spectroscopy datasets. Out of all the ML techniques under test, it was observed that random forest

The Gyrotrons as Promising Radiation Sources for THz Sensing and Imaging

Applied Sciences, 2020
The gyrotrons are powerful sources of coherent radiation that can operate in both pulsed and CW (continuous wave) regimes. Their recent advancement toward higher frequencies reached the terahertz (THz) region and opened the road to many new applications ...

Far‐Infrared Galaxies in the Far‐Ultraviolet [PDF]

The Astrophysical Journal, 2002
In an effort to better understand the UV properties of ultraluminous infrared galaxies (ULIGs), and compare them to the rest-frame UV properties of high redshift sub-mm and Lyman-break galaxies, we have obtained far- and near-UV imaging observations (lambda_{eff}=1457 , lambda_{eff}=2364 , respectively) of two luminous infrared galaxies (LIGs--VV 114

A Review of Textiles Reflecting FIR Produced by the Human Body

AUTEX Research Journal, 2022
The human body constantly produces thermal electromagnetic radiation with a maximum of about 10 μm. This thermal radiation has a number of positive effects on the human body and, in addition, allows the insulation under clothing to be improved under ...

Joint Use of Far‐Infrared and Mid‐Infrared Observation for Sounding Retrievals: Learning From the Past for Upcoming Far‐Infrared Missions

Earth and Space Science, 2023
Atmosphere and surface properties are routinely retrieved from satellite measurements and extensively used in weather forecast and climate analysis. Satellite missions dedicated to fill the gap of far‐infrared (far‐IR) observations are scheduled to be ...

Spatially Resolved Spectral Imaging by A THz-FEL

Condensed Matter, 2020
Using the unique characteristics of the free-electron-laser (FEL), we successfully performed high-sensitivity spectral imaging of different materials in the terahertz (THz) and far-infrared (FIR) domain.

ISO continuum observations of quasars at z=1-4 I.Spectral energy distributions of quasars from the UV to far-infrared [PDF]

, 2000
Eight luminous quasars with $ -30 < M_B < -27$ at z = 1.4 - 3.7 have been observed in the mid- and far-infrared using ISO. All the quasars have been detected in the mid-infrared bands of ISOCAM, while no far-infrared detections have been made with ...
