“…The photobiological effects of UV, VL and IR depend on their wavelength, frequency, mechanism of action and are modified by the thickness, structure, vasculature and pigmentation of skin's stratum corneum , epidermis and dermis ( Figure 1 ) [ 19 , 25 – 29 ].…”

Optical radiation extends between microwaves and X-rays of the electromagnetic radiation and includes ultraviolet (UV), visible light (VL) and infrared (IR) components. The dose of radiation that reaches the skin is influenced by the ozone layer, position of the Sun, latitude, altitude, cloud cover and ground reflections. The photobiological effects of UV, VL and IR bands depend on their wavelength, frequency and mechanism of action. They are modified by the thickness, structure, vasculature and pigmentation of skin's stratum corneum, epidermis and dermis. Following absorption, IR affects the body mainly through transfer of thermal energy to tissues. Visible light and skin interact either thermally or photochemically, whereas UV acts mainly photochemically. Optical radiation in the form of sunlight therapy had been used already in ancient times. Nowadays IR, VL and UV are widely applied in the therapy of allergic, dermatological, cardiovascular, respiratory, rheumatic, neonatal, pediatric and psychiatric disorders.

“…Scattering is greater in the red spectrum and increases progressively towards the infrared section of the spectrum. It influences the depth of photonic penetration into the epidermis and dermis which initiates acute and chronic response in the skin [ 5 , 19 , 20 , 25 , 27 , 30 – 32 ].…”

“…Most indications of electromagnetic radiation having a negative impact derive from fertility research. Studies clearly indicate that sperm motility decreases as a result of radiation, but it was found that this is only one of many factors influencing infertility and not its direct cause [30]. Most studies on the effects of electromagnetic fields on fertility are conducted in men, but they also affect pregnant women.…”

“…Due to the fact that pregnant women have a higher sensitivity to all kinds of dangerous factors, regulations have been introduced to control the employment of pregnant women who might be exposed to electromagnetic fields. Accordingly, pregnant women are not allowed to work in the range of electromagnetic fields with intensities exceeding the values for a safe zone [14,30].…”

This paper summarizes the possibility of employing knitted textile barriers as a shield against electromagnetic fields to protect the human body from their negative impact. Ten variants of knitted fabrics made of electrically conductive yarns, steel, and copper wire that differed in stitch pattern, structural parameters, and raw material, were designed, manufactured, and tested. The knitted fabrics produced differed in structural parameters, including course and wale density, surface density, thickness, thread length in the loop, wale and course take-up, volume cover factor, and surface porosity. These parameters were examined in accordance with the research methodology used in knitting. Barrier measurements were taken in the direction of the wales and in the direction of the courses for two frequencies of electromagnetic fields: 2–4 GHz and 4–7 GHz. It was observed that the shielding effectiveness of the manufactured materials depends on the structural parameters of the fabric, the stiches applied, and the type of yarn.

Terahertz spectroscopy is a promising method to diagnose ocular diseases, where the cornea is typically imaged by Gaussian beams. However, the beam’s mismatch with the cornea’s spherical surface produces a 5-10 % error in analysis. We investigate cornea spectroscopy with wavefront-modified vector beams, reducing the original analysis error to less than 0.5 %. Vector beams are synthesized by our developed 3D Angular Spectrum Method expanded to vector spherical harmonic presentation, allowing wavefront modification and scattering analysis from 100-layer cornea models. We show that wavefront-modified spherical vector beams possess increased accuracy and non-sensitive focusing on cornea spectroscopy compared to the Gaussian beams. Additionally, we investigate wavefront-modified cylindrical vector beams, which show frequency-dependent scattering power arising from s- and p-polarizations. As a result, these beams are unsuitable for cornea spectroscopy, although they have potential for optical force applications. Wavefront-modified vector beams can be applied to spherical target spectroscopy and optical force applications, such as medicine, medical imaging, and optical tweezers.
