This research work reports a low cost method to pattern large area surfaces using soft-lithographic approach through several polymers, particularly with the self-assembly of block co-polymers (BCPs) and also by fabricating ...

In this study, we design and implement an adaptive Underwater Acoustic (UWA) orthogonal frequency division multiplexing (OFDM) system employing adaptive modulation and transmit power. Recently, UWA communications gain more ...

In this dissertation, analysis of near-field regime of thermal radiative transfer in metamaterials supporting surface phonon polaritons (SPhPs) is given. Solutions of electromagnetic fields at subwavelength distances are ...

Strong molecular and aerosol scattering in ultraviolet (UV) wavelengths enable mechanisms where transmitter can communicate with the receiver in the absence of line of sight (LOS) link. Recent advances in solid state ...

Visible light communications is an emerging architecture with unlicensed and huge bandwidth resources, security, and experimental implementations and standardization e orts. Display based transmitter and camera based ...

The presented work proposes a radio frequency (RF) energy harvesting circuit design, which scavenges energy from WLAN dual frequency band. In comparison to other available sources for energy scavenging, e.g. solar, wind ...

Security issues have become major subject along with developments in the speaker verification system. Previous studies have shown that performance is still not fully proven for vulnerability. Simple and easy methods may ...

Demand for high-bandwidth underwater applications such as image and real-time video transmission, has been increasing parallel to the increase in maritime activities such as environment monitoring, navigation, ocean-pollution ...

Recently, with the advancement of technology, there has been a rapid growth of low power wireless devices, such as wireless sensor networks (WSNs) and Internet of Things (IoT). Therefore, the energy requirement for perpetual ...

In many of today's solid-state lighting (SSL) applications, Critical Conduction Mode (CRM) Flyback PFC converter is a popular solution due to its limited component count and simple structure with respect to other switched ...
