Design and Analysis of A Terahertz Microstrip Antenna
Abstract: Terahertz radiation is in the electromagnetic spectrum. Terahertz radiation is used for a variety of purposes since it is non-ionizing and may move in a straight line. It has some similarities with microwaves, in that terahertz radiation can penetrate non-conducting materials, but it shows less depth of penetration than microwaves. Compared to millimeter waves the capacity of Terahertz waves is large enough and possesses high data transmission rates. Terahertz radiation …

Studies in Effect of Alumina Nanoparticles on the Properties of Unplasticized Polyvinylchloride (PVC)
Abstract: AbstractUnplasticized polyvinylchloride (PVC)/nano-alumina composites were prepared using high- speed mixer, two-roll mills and compression molding. In the composite, the concentration of nano-alumina was varied from 0 to 7 phr (parts per hundred). The prepared composites were characterized for mechanical, thermal, electrical, crystallinity and morphological properties. Optimal improvement in properties was obtained at 5 phr concentration of nano-alumina in the PVC matrix. Tensile strength, tensile modulus, flexural strength, flexural modulus and …

Harmonic Estimation and its Compensation using D-STATCOM for a Steel Manufacturing Plant
Abstract: Electrical power system having distorted voltage and current waveform generates harmonics. The compensation of the harmonics is greatly required for better performance of the power system. Harmonic is of major concern for the power system containing electric arc furnace (EAF). Since the nature of the arc is highly non-linear and time varying and therefore harmonic analysis becomes important to know the behavior of the power system. This paper presents the …
