Abstract: The effects caused by disorder, rotating and cutting in left-handed materials (LHM) are investigated. The negative refraction effect and the transmission coefficients of various shapes of LHM are simulated by CST software based on finite integration technique. The Extracted real parts of the permittivity, permeability, and index of refraction for the standard LHM are compared with those of disordered LHM. It is found that the disorder on the split ring resonators results in a lower left-handed transmission and narrower pass bands. The left-handed transmission peak disappears when the cells of LHM are rotated. The cuts of LHM in different directions destroy the properties of LHM in different degrees.
