Rf transmissive electrodes

A reversibly tinting window apparatus comprising:

• a first substrate material layer forming a working electrode;
• a transparent conductive oxide (TCO) material layer disposed on the first substrate material layer;
• a deposition catalyst layer disposed on the TCO material layer;
• an ionic liquid electrolyte layer contained against or adjacent to the deposition catalyst layer;
• a second metallic grating-like structure having a plurality of parallel spaced apart traces and being disposed on or adjacent to the ionic liquid electrolyte layer;
• and
• a second substrate material layer forming a counter electrode and disposed over the second metallic grating-like structure;
• and
• wherein a magnitude of tinting of the apparatus is controlled at least in part by a DC voltage applied across the working electrode and the counter electrode.

A method for forming an optically transmissive window, the method comprising:

• providing a non-electrically conductive substrate;
• forming or disposing a transparent conductive oxide (TCO) material layer, which is transmissive at a selected wavelength or range of wavelengths, on the non-electrically conductive substrate;
• and
• forming or disposing an electrically conductive grating-like structure on the TCO material layer such that the TCO material layer includes a plurality of parallel metallic traces spaced apart by a selected spacing distance.
