A detection method for array antenna element failures is proposed. Compressed sensing is applied to find the solution of array element excitations from measured data. The electric far fields of array ...

This paper presents a 28-GHz 16-element phased-array transmitter for the fifth-generation (5G) new radio (NR) applications, focusing on the power amplifier (PA). The IC was fabricated using a 28-nm ...

A catalytic reaction is an important methodology for the production of pharmaceuticals from the viewpoint of green and sustainable chemistry. Since elemental impurity levels should be controlled ...
