Near-field multiple super-resolution imaging from Mikaelian lens to generalized Maxwell’s fish-eye lens

Abstract

Super-resolution imaging is vital for optical applications, such as high capacity information transmission, real-time bio-molecular imaging and nanolithography. In recent years, technologies and methods of super-resolution imaging have attracted much attention. Different kinds of novel lenses, from the superlens to the super-oscillatory lens, have been designed and fabricated to break through the diffraction limit. However, the effect of the super-resolution imaging in these lenses is not satisfactory due to intrinsic loss, aberration, large sidebands and so on. Moreover, these lenses also cannot realize multiple super-resolution imaging. In this research, we introduce the solid immersion mechanism to Mikaelian lens (ML) for multiple super-resolution imaging. The effect is robust and valid for broadband frequencies. Based on conformal transformation optics as a bridge linking the solid immersion ML and generalized Maxwell’s fish-eye lens (GMFEL), we also discover the effect of multiple super-resolution imaging in the solid immersion GMFEL.

“…Researchers have explored the use of GRIN lenses to focus plane structural waves for optimized energy collection. Environmental vibrations, typically in the far field, can be approximated as plane wave excitations and energy harvested at the lens' focus [20,21]. For instance, Tol et al [22] introduced a GRIN lens that consisted of cylinder arrays with varying height and reported up to triple the power output when a piezoelectric transducer was placed at the lens focus.…”
