Summary:
It is necessary to assure the accuracy of forward calculation with high resolution to acquire accurate image reconstruction. For the forward calculation to be accurate, a fine mesh is used which will accurately determine the electric field everywhere in imaging region. However, due to limited number of measurements can be achieved for any realistic lab-scale system, a coarse mesh with less unknown parameters is required to avoid limited illness and thus can reduce the calculation cost in inverse problem. In this paper, a double mesh scheme in image reconstruction stage is introduced to detect small objects while decreasing calculation cost and assuring the accuracy of the forward calculation.
