چکیده

All the evaluation techniques used to characterize the dielectric properties of materials have similar procedures. The “unknown” material is introduced in a cavity which is considered as a transmission line in order to characterize it measuring insertion looses when an electromagnetic wave passes through it with and without the “unknown” material. The results obtained are analyzed using several differential and/or by comparative methods. The transmission line used in this research was a rigid cylindrical coaxial cavity with a gap in the inner conductor.

Mechanical System Modelling of Robot Dynamics Using a Mass/Pulley Model

The well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. A new model that was previously proposed by the authors that combines a mass with a pulley (MP) is shown to simulat...

Large Lithium Polymer Battery Modeling for the Simulation of Hybrid Electric Vehicles Using the Equivalent Circuit Method

In the present study, a model of a large Lithium Polymer (Li-Po) battery for use in the simulation of Hybrid Electric Vehicles (HEVs) is developed. To attain this goal, an Equivalent Circuit (EC) consisting of a series resistor and two RC parallel networks is considered. The accuracy and the response time of the model for use in an HEV simulator are studied. The battery parameters identifica...

Efficient Analysis of Plasmonic circuits using Differential Global Surface Impedance (DGSI) Model

Differential global surface impedance (DGSI) model, a rigorous approach, has been applied to the analysis of three dimensional plasmonic circuits. This model gives a global relation between the tangential electric field and the equivalent surface electric current on the boundary of an object. This approach helps one bring the unknowns to the boundary surface of an object and so avoid volumetric...

Development of Forward-wave Directional Couplers Loaded by Periodic Shunt Shorted Stubs

In this paper a new procedure for designing forward-wave directional couplers using periodic shunt short circuited stubs is proposed. A new type of cell using these stubs, which enlarge the phase difference between even- and odd modes of a uniform microstrip coupled line is introduced. Using the equivalent circuit model for even- and odd-modes of the proposed cell, the elements of the  ABCD tra...
