  • Phase conversion device for electromagnetic wave
    Patent number: 9531080
    Abstract: A phase conversion device, which converts an electromagnetic wave into a right-handed circularly polarized wave and a left-handed circularly polarized wave to attenuate electric and magnetic effects, includes first, second, and third layers. The first layer includes a ½ lambda wavelength plate. The second layer includes a ¼ lambda wavelength plate. The third layer includes a ½ lambda wavelength plate. The device is effective to reduce an influence of the electromagnetic wave on an electric field and a magnetic field. The device may be portable and useable to reduce an influence of electromagnetic waves on a human body.
