Special Issue Information

Dear Colleagues,

Human health problems have long been one of the main challenges that scientists must face. Cancer in particular, as one of the most common causes of death, is a significant burden of disease worldwide. Indeed, according to the WHO, it accounted for nearly 10 million deaths in 2020. It is well known that early cancer detection is of substantial importance to increase the chances of survival. Cancer prevention and early detection are central to saving lives, reducing financial burden, and improving the quality of patients. To address the abovementioned societal challenges, this Special Issue presents, for the first time to the best of our knowledge, studies and constructions of tissue-like phantom metamaterials with a nanometer fabrication resolution to identify healthy and cancerous areas in real tissues. Currently, the majority of metamaterials only use one degree of freedom (e.g., optical, electrical, and mechanical properties), which are under intense development in laboratories worldwide. This Special Issue aims to deal with metamaterials for industrial applications including clinical practice. These unique and novel nano-opto-electromechanical metamaterial systems offer unprecedented opportunities to control the flow of light in nanoscale structures at high speed and low power consumption. By having a deeper insight into the optical properties of the metamaterials, one may come up with solutions for clinical practice along with phantom cancerous tissues for further research and applications.

Tunable metamaterials belonging to the class of different reconfigurable optical devices have proved to be an excellent candidate for dynamic and efficient light control. However, due to the consistent optical response of metals, there are some limitations aiming to directly engineer electromagnetic resonances of widespread metal-based composites. The former is accomplished by altering the features or structures of substrates around the resonant unit cells only. In this regard, the adjusting of metallic composites has considerably weak performance. Herein, we make a step forward by providing deep insight into a direct tuning approach for semiconductor-based composites. The resonance behavior of their properties can be dramatically affected by manipulating the distribution of free carriers in unit cells under an applied voltage. The mentioned approach has been demonstrated in the case of semiconductor metamaterials by comparing the enhanced propagation of surface plasmon polaritons with a conventional semiconductor/air case. Theoretically, the presented approach provides a fertile ground to simplify the configuration of engineerable composites and provides a fertile ground for applications in ultrathin, linearly tunable, and on-chip integrated optical components. These include reconfigurable ultrathin lenses, nanoscale spatial light modulators, and optical cavities with switchable resonance modes. Full article
