They act like a passive antenna, picking up weak 5G / 6G signals in the air. It captures these signals and collects energy by vibrating / resonating with them. Optical phase shift interface (4); angle of the captured signal waves, array geometry It allows for physical modification and phase shifting of the signal.

The invention's working principle is "Generalized Snell's Law". It is the manipulation of electromagnetic waves based on this principle. The process is as follows: works: Signal Acquisition - Resonance: The weakened base station signal from the external environment, 20 When it reaches the window surface, the conductive meta-atom on the transparent polymer substrate (2) It interacts with the resonance array (3). Each nano- in the meta-atom resonance array (3) The pattern, for example, causes an antenna to resonate at a targeted frequency such as 5G mmWave. It behaves like that, but doesn't consume electricity. Phase Manipulation and Focusing - Phase Shifting: Normally, the glass surface returns the signal 25 It reflects or absorbs. However, the pattern that functions as an optical phase shift interface (4) its geometry causes the wave to propagate at a different phase angle at every point on the surface. This allows the wave to bend instead of bouncing linearly – beamforming. It allows the viewer to turn towards the other side of the window, that is, into the house. Passive Transmission and Protection: A signal that is redirected and focused, protected. It passes through the dielectric coating (5) with minimum loss and the "blind" inside the room It reaches "points". As a result, the external signal strength is not affected by any electronic amplifier. It is "transferred" inside by physical fracture laws without being used.
