In this paper, the performance of Complementary Split Ring Resonator (CSRR) based sensor is explored by varying the geometrical parameters of a sub millimeter crack. Behavior analysis of the CSRR based sensor is performed by variation in the parameters of crack. Variation in resonant frequency of sensor is observed in every case and is noteworthy for our purpose. This signifies the sensor's ability to detect crack of different geometrical parameters on a metal surface.The effectiveness of the sensor is being contemplated through this approach which is appreciable. An illustrious performance of the crack detection sensor has been discovered in this analysis. Simulated results show the feasibility of detecting very small cracks upto 25 μm width, in the metallic surfaces. © 2015 Institute of Advanced Engineering and Science. All rights reserved.

In this work, we propose the design of metamaterial inspired compact circular patch antennas loaded with complementary split-ring resonators (CSRRs) for ISM band operation. CSRRs have been incorporated horizontally inside the dielectric. The various models of CSRR loaded antennas with different patch radius are produced and are evaluated numerically with Ansoft HFSS software. The results of the suggested antenna designs are presented that reveal a comparable impedance match and radiation characteristics with those of a normal patch antenna without CSRR. The proposed antennas yield high levels of miniaturization and similar performance to the conventional patch antenna at the 2.45GHz. © 2015 Institute of Advanced Engineering and Science.
