Latest Patents

One of his latest patents is a method and apparatus for measuring the retardation of composite layers. This invention involves arranging a compensation polarizing plate on the polarization filter layer side of a composite layer sample. The goal is to enhance the polarization characteristics of the sample, which may have an insufficient degree of polarization. The polarization transmission axes of both the polarizing filter layer and the compensation polarizing plate are kept parallel to each other, allowing for accurate measurement of the retardation value and the optical principal axis direction of the sample.

Another significant patent by Nagata is a dielectric constant measuring method and apparatus. This method utilizes a cavity resonator with a transverse slit to measure the dielectric constant of sheet-like materials. The dielectric constant is determined based on the difference in microwave resonant frequencies when the sample is inserted into the resonator. This innovative approach allows for precise calculations of the resonant frequency as the sample is rotated at a designated angle.
