Abstract :
An FDTD method, combined with thin wire and thin slot algorithms used to analyze a metamaterial based on periodic mushroom structures, is proposed. This proposed method is suitable for analyzing problems with fine structural details. Two examples of mushroom structures are investigated to compare the results between simulation and measurement to show left-handed propagation properties. Accuracy of the proposed method is verified compared to the measurement results.
