a The gradient profiles \(\sqrt{{\varepsilon }_{Z}}\) and light ray trajectories of the PHL. Calculated electric field intensity patterns and the corresponding FWHMs in the (b) ML and (c) PHL (d = 132 mm). The red curves represent the normalized electric field intensity along the y-axis at the imaging points (red dotted line). The relative FWHMs of the imaging point are marked. Imaging performance of the (d) ML and (e) PHL where two point sources with a spacing of 0.13λ are placed at the edge of the lens. The ML fails to resolve the two point sources but PHL can resolve clearly. The simulation frequency is f = 11 GHz.
