Real estate pressures in modern electronics have resulted in the need for electrically small antennas, which have subsequently garnered interest amongst researchers and industry alike. These antennas are characterized by their largest dimensions translating to a fraction of the operating wavelength; such a diminutive size comes at the expense of reduced gain and efficiency, and…

Metal housing has been used extensively on portable communication devices such as on mobile phones and tablets.  The choice of metal housing ranges from metallic rim to metallic back cover.  This metal housing tends to improve the outlook appearance of the mobile devices, and add mechanical strength towards the mobile devices.  However, from the aspect…

Underwater Wireless Sensor Networks (UWSNs) are extensively used to explore the diverse marine environment. Energy efficiency is one of the main concerns regarding performance of UWSNs. In a cooperative wireless sensor network, nodes with no energy are known as coverage holes. These coverage holes are created due to non-uniform energy utilization by the sensor nodes…
