Plasma and Metallic Antenna: a Comparative Study
Abstract: Abstract: Plasma antenna is one of the most advanced technologies. The metal antennas used today use a metallic path to direct electromagnetic radiation. Plasma is an ionized antenna. Plasma antenna is a radio frequency receiver device that is made up of plasma segments that activate a surface wave. The importance of this antenna is quick and easy to activate and deactivate, by applying an electric pulse. In this study we …

Detailed Study On Physical Properties Of Silicon Nitride Films Deposited By Plasma Enhanced Chemical Vapour Deposition System
Abstract: Amorphous silicon nitride films have been deposited by radio frequency plasma enhanced chemical vapor deposition (RF-PECVD) technique using silane (SiH4) and ammonia (NH3) as source gases. Investigations have been made in detail to understand the influence of process parameters such as RF power, substrate temperature, gas flow ratio, working pressure etc, on the optical, electrical and surface properties in order to obtain dielectric Si3N4 films for semiconductor device applications. Amorphous …

Plasma Tweeter Loudspeaker - A Singing ARC
Abstract: Plasma arc speaker is a loudspeaker that generates sound without a solid diaphragm by varying the air pressure and utilizing a high voltage arc. It makes sound by heating air that causes air to expand in the same way as in thunderstorm. The grumbles and growls we hear in thunderstorm come from the quick expansion of the air surrounding the lightning bolt due to sudden increase in temperature. This produces …

Intelligent Electromagnetic Synthesis: An AI-Driven IoT Framework for Adaptive Antenna Design in Missile Navigation
Abstract: The rapid evolution of hypersonic and long-range tactical missile systems necessitates antenna architecture capable of maintaining robust communication links under extreme thermal, mechanical, and signal-jamming environments. Traditional antenna design methodologies often relying on iterative simulation cycles and static optimization are increasingly insufficient for the real-time requirements of modern aerospace navigation. This paper proposes an AI-driven, IoT- integrated framework that facilitates autonomous antenna design and performance optimization. By deploying a distributed …

Heavy Metal Exposure in Industrial Workers of Punjab
Abstract: Background: Particularly for those in sectors such textiles, metallurgy, and electronics, heavy metal exposure in industrial environments is a major health issue. A range of negative health effects can result from metal exposure including lead (Pb), cadmium (Cd), chromium (Cr), arsenic (As), and nickel (Ni), including neurological, pulmonary, and renal ones. There is little information available on the degree of heavy metal exposure industrial workers in Punjab, India experience. Objective: …

Investigation of the Modulation of Solar Wind and Communication Signal Waves and its Effect on Earth Navigation System
Abstract: The solar wind is an uninterrupted outflow of magnetized plasma from the solar corona that reaches interplanetary space and accumulates in the earth's outer atmosphere disturbing the navigation and communication systems. Incoming solar winds move across in the space, form waves during times of robust solar activity. These waves undergo modification in Earth's atmospheric and interfere with communication signal. Navi-Aid Airport frequency communication data, together with ACE Satellite Electron and …

Theoretical Study of Surface Waves in Hexagonal Boron Nitride (hBN)
Abstract: Hexagonal boron nitride (hBN) is a wide bandgap semiconductor material in which Boron (B) and Nitrogen (N) atoms form hexagonal structure and has number of robust properties of technological importance. Boron nitride nanotubes (BNNTs) are very nice area of research in recent years. Its structure is similar to carbon nanotubes (CNTs) where carbon atoms are arranged in hexagon. hBN is also known as White Graphene. Various methods are employed to …
