Abstract: The free-space wavelengths in the 300-GHz band are so short that it is extremely challenging to realize phased arrays with a half-wave antenna pitch, required for preventing grating lobes.
A polymer with a 2D molecular structure stacks into tightly packed layers — forming films of nanoscale thicknesses that are nearly impermeable to gases and moisture. Polymers are attractive barrier ...
