Abstract The NiCr micro-heater is a key element of MEMS-based electro-explosive device (mEED), while electrostatic discharge (ESD) may excite the accidentally. To discover mechanism that how ESD excitations effect on heat response performance micro-heater, electro-thermal conversion process was numerically modelled by using commercial software. Three different shapes micro-heaters, including re...

Nonlinear Bending Analysis of Micro/Nano Rectangular and Annular Sector Plates Using a Modified Higher-Order Shear Deformation Theory the Couple Stress

In this paper, the bandwidth of rectangular Microstrip antenna is enhanced by ‘I’ slotted rectangular microstrip patch antenna. In some applications which the increased bandwidth is needed, proposed antenna is one of the alternative solutions. The proposed antenna has been designed at the 2 GHz frequency. The frequency band of proposed antenna is in between (1.64-3.26 GHz) the fractional bandwi...

The CORDIC algorithm provides an efficient method of computing trigonometric functions by rotating a vector through some angle, specified by its coordinates. This rotation is obtained by performing a number of micro rotations through elementary rotation angles, into which the total rotation angle has been decomposed. This paper presents the design and implementation of a runtime reconfigurable ...

Knowledge of flow pattern and flow pattern transitions is essential to the development of reliable predictive tools for pressure drop and heat transfer in two-phase micro-channel heat sinks. In the present study, experiments were conducted with adiabatic nitrogenwater two-phase flow in a rectangular micro-channel having a 0.40632.032 mm crosssection. Superficial velocities of nitrogen and water...

A very simple approach for bandwidth enhancement, reducing the mutual coupling and return loss of 1x2 rectangular patches multiple inputs and multiple outputs (MIMO) antenna for Wi-Max operation is proposed. Resonate frequency of proposed antenna is 6.2GHz. For enhancing the bandwidth a simple rectangular slot has been used and bandwidth is enhanced from 3% to 13% at -11dB of return loss. For r...

A Rectangular to Polar coordinate converter based on scaling free vectoring CORDIC is proposed in this research paper. Polar coordinates are most appropriate for the systems displaying radial symmetry. Here scaling free CORDIC algorithm operating in vectoring mode computes Polar coordinate of input vector i.e. absolute magnitude and phase angle from its rectangular coordinate. Using this algori...

The spring constant of an atomic force microscope cantilever is often needed for quantitative measurements. The calibration method of Sader et al. [Rev. Sci. Instrum. 70, 3967 (1999)] for a rectangular cantilever requires measurement of the resonant frequency and quality factor in fluid (typically air), and knowledge of its plan view dimensions. This intrinsically uses the hydrodynamic function...

A plastic, 95-GHz rectangular waveguide with an integrated plastic flange has been successfully demonstrated using micro hot embossing and electroplating technologies. Two prototype devices with integrated flanges on both ends have been tested using an Agilent PNA 5250 network analyzer. The prototype with non-metallized flange shows return loss s11 and insertion loss s21 values of −21.5 and −1....
