Based on two-dimensional LC network, a zero-electric and zero-magnetic material (ZEM) focuser is designed, and the equivalent node voltage distribution matrix is derived. The focuser with triangular, quadrilateral, hexagonal and octagonal contours is investigated, and the effects of shape and size on its performance are simulated. The results show that, the focusing effect is independent of the shape of the focuser when the size of the focusing area is smaller than twice the wavelength; energy at the focus point increases gradually with the focusing area; when the size of the focusing area is bigger than twice the wavelength, the main focusing area disappears and a number of sub-focusing points are generated at the same time.
