A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...

Abstract Recently, MXenes stand out as an attractive type of two-dimensional layered material. Their unique deformable surface terminations and rich chemical compositions endow with adjustable customizable characteristics, resulting in excellent linear/non-linear electromagnetic wave responses versatile applications. In order to get more insights this area, here, we make a comprehensive summari...

Snowfall is an important component of the Earth’s precipitation and hydrological cycle. Remote measurements of frozen hydrometeor properties have been limited because coincident measurements of microphysical and electromagnetic properties of snowfall have not been available. Ground-based radars have been widely used to monitor snowfall intensity, but even those measurements are difficult to rel...

Temporal characteristics of the localized damage development initiated by a short-time impact pointed loading SiC ceramics which is widely applied as protective material against shock action upon engineering constructions and people were investigated. The statistics crack nucleation relaxation was studied with methods acoustic emission electromagnetic emission, correspondingly. It shown that le...

Presented is an original study about the effects of integrated circuit aging on electromagnetic emission and immunity to radio frequency interferences. For the first time an electromagnetic compatibility (EMC) qualification procedure is proposed to quantify the EMC level variation over the full lifetime of a component. Results presented show non-negligible variations of the emission and immunit...
