  16. Conclusion • A new meander open complementary split ring resonator particle based on the open complementary split ring resonator particle has been presented. • It has been shown that the MOCSRR particle has a lower resonant frequency than the OCSRR particle with similar over all dimensions. • Also, the equivalent circuit for various OCSRR and MOCSRR particles was extracted and presented. • These results showed that in certain circumstances is was possible to predict the resonant frequency of the particle. • Finally, this was followed by a discussion on antenna design using the MOCSRR particles.
