This research has underlined the need to recognize that the effect of specific solvents on the printing plate material can be different for fine printing elements/details on print and the solid ink film area. Depending on the properties and purpose of the image to be printed, optimization of ...
Innovative electromagnetic structures, such as metamate- rials and electromagnetic band gap (EBG) structures, are employed to control the coupling between antenna elements [27]. Yet challenges persist, especially in terms of integrating multiple antennas into com- pact portable devices. The potential ...
