Next-generation wireless networks are facing increasing demand for high data rates, low latency, and seamless connectivity. To address these challenges, a multi-hop hybrid communication system integrating Free Space Optics ...

Detection and monitoring of airborne hazards using e-noses has been lifesaving and prevented accidents in real-world scenarios. E-noses generate unique signature patterns for various volatile organic compounds (VOCs) and, ...

The development of the Internet of Things (IoT) technology and their integration in smart cities have changed the way we work and live, and enriched our society. However, IoT technologies present several challenges such ...

In this article, a low-profile microstrip patch antenna using an FR-4 substrate with relative permittivity of 4.4 and thickness of 1.6 mm is designed. On the top of a substrate, it consists of one metallic hexagonal patch ...

Cervical cancer is a critical imperilment to a female's health due to its malignancy and fatality rate. The disease can be thoroughly cured by locating and treating the infected tissues in the preliminary phase. The ...

In this paper, a low cross-polarization level, low radar cross section (RCS), conformal, ultra-wideband, polarization-insensitive absorber utilizing sinusoidal periphery annular ring (SPAR) resonator based novel resistive ...

In this paper, a planar tag antenna for UHF band RFID composed of a spiral ending meandered line with meandered inductive loop is presented. The presented novel compact spiral ended meandered tag having double sided meandered ...

This present work describes the fabrication of silicon heterojunction (SHJ) solar cells as a proof-of-concept scheme on an adequately thin ( $30 ~\mu \text{m}$ ) n-type crystalline silicon (c-Si) wafer as the active layer. ...

Long Range (LoRa) has become a key enabler technology for low power wide area networks. However, due to its ALOHA-based medium access scheme, LoRa has to cope with collisions that limit the capacity and network scalability. ...

Through-the-wall radar images suffer from strong clutter due to the presence of dielectric walls and environmental noise. Several approaches have been explored to reduce clutter for detecting targets with similar dielectric ...
