The derived analytical formulas allow us to easily find the physical dimensions of conductive patterns which implement the required surface impedance. Numerical verification of the method shows excellent agreement with the analytical predictions, allowing the design of an arbitrary impedance without any optimization process. The method can be applied for designing lossy and low-loss metasurfaces which can be used for absorption and wavefront manipulation of electromagnetic waves.
