This letter presents a new low-profile, reconfigurable pattern antenna. The antenna features a printed circular segmented loop fed by two separate feed points coupled to a parasitic composite ...

In large doses, radiation can cause serious tissue damage and increase a person’s risk of later developing cancer. The low doses of radiation used for imaging tests might increase a person’s cancer ...

“The current study explores the performance of monofacial and bifacial solar panels on various roof typologies with variable installation patterns and albedos ... at this rate appears to be triggered ...

Extreme-high UV-B radiation hits Hungary – protect yourselves! Photo: MTI (taken in front of the Nyugati railway station in Budapest). While it’s still too early to provide an exact weekend forecast, ...

We present a method to transform the radiation pattern of an antenna into an arbitrarily defined pattern through the use of an inhomogeneous spherical impedance metasurface that completely encloses ...
