    • The invention is directed to polarizing devices that can be scaled to polarize electromagnetic radiation having wavelengths in ultraviolet to microwave range; and more particularly to devices suitable for use at visible and IR wavelengths. The device has a length, a width and a thickness, and a patterned system of channels, voids or holes embedded in or through a glass matrix and running through the thickness of the glass to thereby polarize incoming electromagnetic radiation having two polarization modes orthogonal to one another, blocking the passage of or reflecting one mode and permitting the other mode to pass through the device. The glass can be any glass suitable for transmitting the electromagnetic radiation in the range it will be used without excessive transmission losses due to absorbance of radiation in that range by moieties present in the glass. In one aspect, the device according to the invention may be deemed a "universal" polarizer: in the sense that it can be made to work in wavelength ranges from the microwave to the ultraviolet. The devices can also be made of polymeric materials utilizing the principles enumerated in the specification.
    • 本发明涉及可以缩放以使具有紫外至微波范围内的波长的电磁辐射极化的偏振装置; 更具体地涉及适用于可见光和红外波长的装置。 该装置具有长度,宽度和厚度,以及嵌入或穿过玻璃基体并贯穿玻璃厚度的通道,空隙或孔的图案化系统,从而使具有两个正交于一个偏振模式的入射电磁辐射偏振 另一种方式是阻止或反射一种模式并允许另一种模式通过设备。 该玻璃可以是任何玻璃,其适用于在将被使用的范围内传输电磁辐射,而没有由于玻璃中存在的部分的辐射在该范围内的吸收而​​造成的过度传输损失。 在一个方面,根据本发明的设备可以被认为是“通用”偏振器:就其可以被制成在从微波到紫外线的波长范围内工作而言。 该装置也可以利用说明书中列举的原理由聚合物材料制成。
