“…The analytical results of super-resolution imaging agree well with the numerical results. In addition, due to the impedance mismatching between SICSL and the air interface, the whispering gallery modes (WGMs) [11] are excited and affect the imaging quality. We clarify the relation between the resolution and exciting WGMs by solving the eigen equations of SICSL.…”

Super-resolution imaging with superlens has been one of the fundamental research topics. Unfortunately, the resolution of superlens is inevitably restrained by material loss. To address the problem, we introduce the solid immersion mechanism into the slab superlens and the cylindrical superlens. The proposed solid immersion slab superlens (SISSL) and the solid immersion cylindrical superlens (SICSL) can improve resolution by converting evanescent wave to propagating wave using high refractive index materials. From the perspective of applications, the cylindrical superlens with finite cross section and the ability of magnification or demagnification has more advantages than slab superlens. Therefore, we focus on demonstrating analytically the super-resolution imaging of SICSL. Due to the impedance mismatching caused by solid immersion mechanism, the whispering gallery modes (WGMs) are excited between SICSL and the air interface. We clarify the excitation conditions of WGMs and analyze their influence on the imaging quality of SICSL. The SISSL and SICSL may pave a way to apply in lithography technique and real-time biomolecular imaging in future.

“…One of the main issues lies on the role of wave drain/sink and how it contributes to subwavelength imaging. Furthermore, a recent experiment in liquid setup provides further insights on super-resolution to which evanescent waves other than wave drains may contribute [24]. Before coming to the numerical results, we remark on the super-resolution and wave drain to clarify our simulation setup.…”

Maxwell fisheye lens was proposed to reach superresolution with the addition of wave drain and the interaction of multiple drains is theoretically predicted to improve subwavelength resolution further. In this paper we discuss the role played by port drains in optical absolute instruments, and verify by full-wave simulation that coupling nature for wave source and drain applies correctly in the picture of scanning imaging for absolute instrument. This work prospects for scanning near fields shaped from far-field wave propagation.

“…Gradient refractive index (GRI) lens has been developed rapidly for its excellent capability to control the propagation of electromagnetic waves [29][30][31][32][33] and enable focusing or imaging. [34][35][36][37][38][39][40][41] Among these GRI lenses, the Mikaelian lens (ML) as a self-focusing cylindrical medium was derived firstly by Mikaelian in 1951 [42] and has drawn much attention, due to its property of self-imaging in geometrical optics. [43,44] Many applications based on the Mikaelian lens were designed and fabricated from microwave frequency to optical frequency.…”

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.
