The corresponding equivalent circuit parameters were calculated and a lumped equivalent circuit of the ME tunable coupling microstrip bandpass filter was established. The insertion loss of the ...

The combination of microwave-induced pyrolysis and mechanical processing is a promising way to recycle the waste printed circuit boards (WPCBs). In pyrolysis, WPCBs yield an average of 78.6 wt.% so ...

MATERIALS AND METHODS Printed circuit boards used in this research were collected by a waste electronics recycling center in the city of São Paulo - Brazil. Initially the manual dismantling of the ...

The differential-mode signals in printed circuit board (PCB) traces are unlikely to produce significant amounts of radiated emissions directly; however these signals may induce common-mode currents on ...
