Abstract: A device for enhanced microwave permeability through a coated transparent substrate includes a first surface of the device and a second surface of the device each forming an exterior boundary of the device. The device includes a first section extending through the device from the first surface to the second surface. The first section enhances a permeability of a first microwave band through the coated transparent substrate. The device also includes a second section extending through the device from the first surface to the second surface. The second section enhances a permeability of a second microwave band through the coated transparent substrate. The device further includes a third section extending through the device. The third section includes a location where the first section and the second section merge. The third section enhances a permeability of a third microwave band through the coated transparent substrate.

Abstract: A device for enhanced electromagnetic communication through a coated transparent substrate is provided. The device includes a first transparent conductive (TC) layer having a first surface and a second TC layer having a second surface. The first surface is parallel to the second surface. The device also includes a first section extending through the first TC layer from the first surface and aligned with an axis that extends from the first surface to the second surface. The first section is configured to enhance electromagnetic communication through the coated transparent substrate. The device further includes a second section extending through the second TC layer from the second surface and offset from the axis that extends from the first surface to the second surface. The second section is configured to enhance electromagnetic communication through the coated transparent substrate.

Abstract: An electrochromic device is disclosed. The electrochromic device can include a stack of layers. The stack of layers can include a first transparent conductive layer on a substrate, a second transparent conductive layer, a cathodic electrochromic layer between the first transparent conductive layer and the second transparent conductive layer, and an anodic electrochromic layer between the first transparent conductive layer and the second transparent conductive layer. The stack of layers can be patterned. In one embodiment, the pattern can be parallel to a voltage gradient of the electrochromic device. In another embodiment, the pattern can extend through all layers of the stack of layers of the electrochromic device.
