| Abstract: | Metamaterial energy harvester based subwavelength imaging structure is presented. Besides, 2×2 array patch antenna is designed to create incident radiated signal towards the proposed harvester structure. Harvested energy is converted to DC voltage signal by using Schottky diodes and each cell is represented by 256 grey levelled pixel value. Therefore, any incident electromagnetic wave placed in the operating frequency range can be monitorized. In the experimental study, experiments are realized with and without antenna to investigate the effects of instantaneous electromagnetic waves and the observed images. Afterwards, another experiment is conducted to observe the effects of metal plate which is located between the antenna and the harvester structure. The last experiment is performed by using a Yagi Uda antenna for sub-wavelength imaging. The proposed harvester structure can be used in various applications such as energy harvesting, incident wave tracing, crack detection, spy device detection, medical imaging, and so on. |
