Reconfigurable intelligent surface (RIS) is a key technology to enable the concept of smart radio environment (SRE) which envisioned meet ever-increasing demands connectivity in upcoming decade. However, most existing works consider RIS that seen as whole surface. In this paper, we study performance consists multiple tiles, each capable performing certain wave manipulation, by deriving physics-compliant analytical formulation received signal at receiver. We also introduce numerical...
Orthogonal Frequency Division Multiplexing (OFDM) merupakan teknik modulasi multicarrier yang banyak diadopsi oleh berbagai teknologi komunikasi nirkabel untuk memenuhi kebutuhan akses broadband kian meningkat karena menyediakan transmisi dengan data rate tinggi. Selain itu, OFDM juga tahan terhadap efek multipath fading. Salah satu permasalahan utama pada sistem ini adalah tingginya nilai PAPR menyebabkan penggunaan power amplifier menjadi tidak efisien. Sebagai solusi ini, Selected Mapping...
This paper presents about design of mobile-based data integration application system from one radar station for displaying information objects detection results multiple object locked by tracking needs, AIS receiver data, long range camera monitoring and also weather information. The proposed in this can be a guidance commander taking decision. A sample implementation the is given.
Artificial Intelligence (AI) plays an important role in the world of robotics because it allows robot can move automatically with just a few simple commands. In order for development more advanced robotics, researchers are trying to make perform variety sports and games. One that entered is football. The following studies attempt simulate soccer game two dimensions simulator (2D Simulator) runs on RoboCup™ Soccer Simulator. this paper, authors propose design characterization algorithm...
This paper describing about the tool made by author that used to measure emission of CRT (cathode ray tube) for televisions and monitors, can be as a Injector. The purpose design manufacture this is learn electrons on screen RGB cathodes are part producing an image emitted electron gun screen. Which often subject corrosion. For has working principle eliminate corrosion cathode balancing beam from it will back good usual. also in color or monochrome television monitor oscilloscope. divided...
This paper describes about how a mobile phone can be piece of equipment or tools used by student to identify various kinds insect. application help their observations and instantly analyzed with quite lot data but fairly simple method that is key determinant Development usually conventional print media, whether books sheet form not practical taken students. To address these difficulties, the determination developed which based J2ME installed on phones. The was specifically insects students...
Blank spots are an important problem that must be overcome in wireless communication. Metamaterials, with their ability to reflect electromagnetic signals good efficiency, believed able this problem. In paper, a metamaterial circular patch unit-cell for reflector applications operates at frequency of 3.5 GHz is proposed. Software analysis (CST) used optimize the unit cell and see its performance as reflector. The research results obtained 91.4% reflected power percentage, 0.005% absorbed...
We present the design and analysis of a Huygens' metasurfaces for beam-splitting applications in K-band. The metasurface consists three dielectric substrates with four etched metallic layers is designed to operate at center frequency 25 GHz. By independently manipulating electric magnetic resonances through variation geometries, device efficiently splits incident beams two different refraction angles. Here, we provide preliminary numerical simulations device, emphasizing its relevance...
This paper presents a performance comparison of the circular patch unit cell as for reflector application at 3.5 GHz frequency using dielectric substrate between FR4 and F4BMX220 substrates. A is chosen because it commonly used, fabricated, has wider bandwidth compared to other structures. on both substrates presented in graph S-parameters, reflection phase, operating bandwidth, well table dimensions, where result performed by simulation CST software. Based simulated results, better terms...
