Because of its special chemical structure, it possesses many unique physical and chemical properties , such as far-infrared radiation
[7, 8] and negative ion release [9, 10].
A single-layer model for far-infrared radiation
drying of onion slices.
(FIR), which comprises electromagnetic waves of wavelength 3-1000 [micro]m , possesses physiological actions because not only of its high penetrating power in human tissue but also of its ability to elicit both heat-related  and nonheat-related  biological effects.
Improvement of quality and antioxidant properties of dried mulberry leaves with combined far-infrared radiation
and air convection in Thai tea process.
Initial inspection of the observations has revealed that many emit bright far-infrared radiation
(4.) Discussion Meeting Issue 'The terahertz gap: the generation of far-infrared radiation
and its applications' organized by A.
This method is based on the transmission of polarized far-infrared radiation
. Fairly thick samples (polyethylene up to one centimeter thick) can be tested easily with this nondestructive approach.
