Sub-Wavelength Slit-Assisted Binary Metallic Lens Design for Effective Multifocusing via Phase Superposition Method
This paper proposes a multifocal lens design method named phase superposition method (PSM) and a methodology to increase the efficiency of metallic binary zone plates through a sub-wavelength slit array. The phase superposition method calculates the intensity at each focus, assuming a perfectly phas...
