Latest Patents
Mridula holds a patent for a method to design a security feature on the substrate of security documents using sub-wavelength grating. This invention claims a method of designing a security thread in security documents that offers better color contrast at any viewing angle. The invention involves the use of sub-wavelength gratings with a period and thickness less than the wavelength of light. These gratings are preferably asymmetric, designed to ensure that the O-order reflections are of longer wavelengths (red) while the higher-order reflections (diffracted orders) are of shorter wavelengths (blue/green). The resulting security thread provides improved color contrast compared to the rainbow colors of prior art, allowing for easier distinction of authentic documents.
