Sine-Wave Oscillator for Reflexotherapy Device

Abstract

Results of numerical modeling of the binary difractional optical elements (DOE, lenses) operation within the framework of strict electromagnetic theory are presented. Operability of the binary lenses is investigated for the cases when the aperture radius is about ten times of the wavelength and the focal distance varies from the half to two times of the wavelength For the first time the possibility to obtain the resolution of less than the half of the wavelength is demonstrated. The operability of DOE is also revealed for the wavelengths that are different from the designed.
