1. An energy-efficient signal-transparent window assembly comprising:
a window substrate; and
a stack, the stack comprising:
a first dielectric layer disposed over the window substrate;
a conductive layer disposed over the first dielectric layer such that the first dielectric layer is disposed between the conductive layer and the window substrate, wherein the conductive layer is formed by multiple disjoined structures separated by gaps;
a barrier layer disposed over the conductive layer such that the conductive layer is disposed between the first dielectric layer and the barrier layer; and
a second dielectric layer disposed over the barrier layer such that the barrier layer is disposed between the second dielectric layer and the conductive layer, wherein:
the first dielectric layer, the conductive layer, the barrier layer, and second dielectric layer form a plurality of primary stacks and a plurality of secondary stacks over at least a portion of the window substrate,
the plurality of secondary stacks forms a pattern, defined by pattern lines extending between each adjacent pair of the plurality of primary stacks such that each of the pattern lines has a width smaller than 100 micrometers, and
each of the plurality of primary stacks has an enclosed shape, defined by the pattern, with a dimension smaller than 10 millimeters in any direction parallel to the window substrate.
