In this paper, we propose a new miniaturized Artificial Magnetic Conductor (AMC) for Dual Wide Band operation for Long Term Evolution (LTE) Europe bands. By a patch design, the AMC is proposed in mono band. Next, a square slot is added to achieve a Dual Wide Band AMC (DWBAMC) operation. At the beginning, this design proved to be of a large unit cell. This problem is later solved by reducing the unit...
Lebanon witnessed one of its biggest dangerous environmental crisis due to the oil spill caused by Israel bombard of fuel storage tanks in war 2006. Official reports stated that around 15000 tons of heavy fuel oil spilled in sea water. The spill threatened the maritime and human life and caused severe environmental disasters. On an international scale, the European Space Agency (ESA) stated that more...
This paper presents a step-by-step procedure to extract the effective permittivity of dry and wet snow in an electromagnetic simulator. The S-parameters are extracted using HFSS (High Frequency Structure Simulator), which is a Finite Element Method (FEM) full wave simulator. The permittivity curve is calculated using the S21 retrieval method. The calculated permittivity is compared with theoretical...
This paper is dedicated to study and compare the behaviors of conventional split ring and S-shaped resonators for designing Artificial Magnetic Conductor. S-Shape resonator is proven more technical and proficient considering its geometrical characteristics. The design can be used for communication application in Long Term Evolution bands. Results are obtained by ANSYS HFSS (High Frequency Structure...
A branch-line coupler (BLC) working at three arbitrary frequencies using double-Lorentz (DL) transmission line (TL) Metamaterial is presented. A DL has sufficient degrees of freedom to realize tri-band microwave devices. We demonstrate that the three operating frequencies can be obtained by tuning the phase slope of the line section. Then, the design equations are extracted and validated for the first...
An arbitrary tri-band transmission line (TL) using double-Lorentz (DL) metamaterial medium is presented. A DL TL has sufficient degrees of freedom to realize tri-band microwave devices. We demonstrate that the three operating frequencies can be obtained by tuning the phase slope of the line section. Then, the design equations are extracted for the first time and validated by Surface Mount Technology...
