Abstract Fresh water available on earth is very scared. Yet the demand of fresh water is incessantly increasing, due to population growth and rapid industrialization. According to the United Nations, in 2025, 63% of the world’s population will be living in scarce water areas. The provision of freshwater is becoming a gradually more important issue in many areas of the world. Oceans are the only available source for large amount of water. Ocean water presents high salinity, so there is a need to desalinate ocean water for everyday consumption. Solar stills are widely used in solar desalination for being very simple… More >

Abstract Metamaterial resonators are electrically small resonant particles useful for the implementation of effective media metamaterials. In this paper, some applications of metamaterial resonators (such as the split ring resonator -SRR-, the complementary split ring resonator -CSRR-, the folded stepped impedance resonator -SIR-, and the electric LC resonator), that exploit the symmetry properties of transmission lines loaded with such symmetric particles, are reviewed. This covers differential (balanced) lines with common mode suppression, linear and angular displacement sensors (including alignment sensors), angular velocity sensors, and radiofrequency barcodes. Advantages and drawbacks as compared to existing implementations are also discussed. More >
