Abstract In this article, bandwidth enhancement of a microstrip patch antenna using new kind metasurface is discussed. This geometry used to generate resonances in and with an optimal position the relation we can overlap obtain large bandwidth. The proposed showed from 5.1 GHz 8.0 what it able be applied WiFi 5 6. Numerical results were obtained Ansys HFSS software. A prototype was built measur...

Many existing phenomena in nature are considered new design ideas in various fields of industry. Bionics is the application of biological methods and systems found in nature to the study and design of engineering systems and modern technology. By performing bionic review, the researchers found the penguins by delivering air locked under their wings and creating air bubbles, the drag significant...

In the present paper, some finite element softwares about interaction of dam and reservoir during earthquake in time domain are discussed. Impedance option is used as boundary condition of absorbent of reservoir and wave. For each software, time history analysis of pressure and displacement are done and finally suitable elements for dam structure and reservoir fluid are introduced comparing the...

Microelectromechanical Systems (MEMS) is the technology of the very small, and merges at the nano-scale into "Nanoelectromechanical" Systems (NEMS) and Nanotechnology. MEMS are also referred to as micro machines, or Micro Systems Technology (MST). MEMS are separate and distinct from the hypothetical vision of Molecular nanotechnology or Molecular Electronics. MEMS generally range in size from a...

In this study, callus formation strengths of the rat femurs are examined after bone fracture healing using the computer aided finite element methods. The rat femurs are modeled using computed tomography (CT) images using both MIMICS R12 and GEOMAGIC software for finite element applications for which ANSYS Workbench is employed. The mechanical properties of rat femurs are obtained using the thre...

In this research paper design and analysis of wire ropes used in elevator have been presented. The main objective study is to find the best practices on handling for safety reduce downtime elevators due rope failures. Design calculations done calculate apt dimensions constructed Auto Desk inventor software performed using Ansys. Two configurations studied from result it can be concluded that po...
