Filter is very essential component in wireless communication system. Since need of compact devices is increasing day by day, Filter plays very important role in developments of such devices. In this paper, multiband micro strip stepped impedance resonator band pass filters operating in range of 1 to 10 GHz are designed. A series capacitively coupled series micro strip line resonator is modified...

Flexible flapping wings have garnered a large amount of attention within the micro aerial vehicle community: a critical component of computationalmicro aerial vehicle simulations is the representation of the structural dynamics behavior of the flapping-wing structure. This paper discusses the development of a new nonlinear finite element solver that is based on a corotational approach and suita...

In this paper, we present a 3D lattice Boltzmann BGK model for simulation of micro ows with heat transfer. This model is an extension of the two-dimensional model that is based on the kinetic theory and the thermal lattice Boltzmann method. The kinetic relations of the relaxation times in this model were linked with the Knudsen number, and a di use scattering boundary condition for the velocity...

Miniature 250 to 700-μm tall copper air-filled rectangular coaxial line with inner conductor supported by periodic dielectric straps is demonstrated. The measured loss is as low as 0.08dB/cm at 37GHz, while the isolation between two parallel lines with center-to-center separation of 350μm is better than 60dB. A number of quasi-planar components are designed to be fabricated on the same 6inch wa...

We discuss the fast-reaction limit of a two-scale reaction-diffusion model. We point out that if the reaction constant a explodes to infinity, then a two-scale PDEs system with free boundary at the micro cell is obtained. The aim of this note is to answer the question: Can the same two-scale free-boundary problem be obtained if we first pass to the fast-reaction limit a → ∞ and then take the ho...

An analytical model by Lefèvre and Lallemand (1) that couples a 2D hydrodynamic model for both the liquid and the vapor phases inside a flat micro heat pipe (FMHP) and a 3D thermal model of heat conduction inside the FMHP wall has been modified. It consists of superposing two independent solutions in order to take into account the impact of evaporation or condensation on the equivalent thermal ...

This reaffirmation of teachers has been a leading factor in the development of recent strategies for school improvement The reports by the Carnegie Task Force and the Holmes Group are two prominent examples of proposals aimed specifically at problems within the teaching profession. These reports are significant in that they have helped place teaching squarely at the center of current educationa...
