A method enables a gas turbine engine variable bypass valve system to be assembled. In one aspect, the polarization structure includes a retardation layer and a plurality of nanowires formed on the retardation layer. In certain embodiments, cells are activated and expanded to very high numbers of cells in a short period of time. The controller switch automatically switches the output signals of the input devices between the output ports when a switch command signal is received from the selected port. as well as a method for their preparation are disclosed herein.
