The application of Ku-band VSAT Systems to single layer hexagonal micro strip patch antenna is thoroughly simulated in this paper. The radiating elements in this antenna are composed of two triangular and one rectangular slots from the conventional micro strip patch antenna. These slots are engraved in the rectangular and triangular patch, joined together in two structures, and by single probe ...

Thermo-elastic damping is a significant dissipation mechanism in high quality factor microstructures. In this paper, thermo-elastic damping of the in-plane vibration of fully clamped rectangular micro-plates has been studied. The governing equation of the micro-plate motion and heat conduction equation were derived. Then, The Galerkin method has been used to solve the coupled heat-displacement ...

In this paper a very simple micro-strip rectangular patch antenna is proposed with circular polarization and enhanced bandwidth for mobile Ad Hoc network. By using the orthogonal feed orthogonal linear components has been produced having phase difference of odd multiple of 90 ̊. For enhancing the bandwidth the rectangular patch has been truncated. The bandwidth of antenna is 12%. The proposed an...

This paper explores several issues important to the thermal design of single-phase and two-phase micro-channel heat sinks. The first part of the paper concerns single-phase heat transfer in rectangular micro-channels. Experimental results are compared with predictions based on both numerical as well as fin analysis models. While the best agreement between predictions and experimental results wa...

In this paper, we provide a novel micro rectangular-shaped long-period fiber grating (MRSLPFG) coated with Fe₃O₄ nanoparticles as the sensing material and packaged in polydimethylsiloxane (PDMS) for magnetic sensing application. The micro rectangular-shaped grating structures are fully dip coated with the magnetic fluid and heated to form a thin solid film. This thin overlay is used as the sens...

Understanding the flow fields at the micro-scale is a key to develop methods of successfully mixing fluids for micro-scale applications. This paper investigates flow characteristics and mixing of three different geometries in micro-channel. A Circular groove micro mixer has been designed and simulated. One such channel is shown in Figure1. The geometry of the channels taken was rectangular with...

For the first time, two dimensional (2D) rectangular Co3O4 with micro-/nanoarchitectures is successfully synthesized by a facile hydrothermal treatment with the assistance of poly(diallyldimethylammonium chloride) (PDDA). Owing to the strong electrostatic interaction, positively charged PDDA molecules are considered as structure directing agents and play a crucial role in the formation of the u...

This paper present the improvement in gain of micro-strip patch antenna, which is used with Circular, Rectangular and Square shaped split ring resonator designed at a separate substrate at height 0.05mm from the ground plane. In spite of design complexity it is easy and commercially cheap way of enhancing gains of micro-strip antenna. Simulations have been performed using High Frequency Structu...

Adenosine triphosphate (ATP) is known to be released from the erythrocyte in an oxygen (O2) dependent manner. Since ATP is a potent vasodilator, it is proposed to be a key regulator in the pathway that mediates micro-vascular response to varying tissue O2 demand. We propose that ATP signaling mainly originates in the capillaries due to the relatively long erythrocyte transit times in the capill...
