چکیده
|
As a crucial optical element, many different kinds of microlens have been proposed and studied. in this paper, a 2-dimensional microlens has been achieved based on direct bending of wavefront. with only 25 elements, the microlens can achieve subwavelength imaging in a 2-dimensional case. focusing pattern and sensitivity of object movement have been studied. the physical picture for focusing and imaging has been explained by the help of a gauss dipole model. current study can broaden the basic understanding on light-matter interaction and optical element design.
