The thermal resolution of a camera can be improved by time, space and frequency processing. In the first part, the efficiency of such processing is compared for a given camera, using an extended blackbody. In the second part, the processing are applied to the improvement of the radiation pattern determination of an X-band horn using the EMIR technique.

background: over the past few years, the rapid use of high frequency electromagnetic fields like mobile phones has raised global concerns about the negative health effects of its use. adaptive response is the ability of a cell or tissue to better resist stress damage by prior exposure to a lesser amount of stress. this study aimed to assess whether radiofrequency radiation can induce adaptive r...

Weak gravitational lensing is responsible for the shearing and magnification of the images of high-redshift sources due to the presence of intervening mass. Since the lensing effects arise from deflections of the light rays due to fluctuations of the gravitational potential, they can be directly related to the underlying density field of the large-scale structures. Weak gravitational surveys ar...

We report on the theoretical calculations considering collinear electromagnetic radiation at the propagation of an optical pulse through a slab of nonlinear material. Calculated waveforms of the radiated field fit well to the experimental dependencies showing the remarkable similarities between the radiation at nonlinear wave interaction and the radiation phenomena of moving external charges, s...

Complicated environmental problems inevitably arise when technology advances. One major environmental problem is the presence of electromagnetic radiation. Long-term exposure to electromagnetic radiation can damage people’s health in many ways. Therefore, this study proposes producing composite boards with electromagnetic shielding effectiveness and thermal insulation by utilizing the structure...
