Equivalent circuit of a reconfigurable triple-slot reflectarray cell
Abstract : This paper presents an equivalent model for a multiple-resonance reflectarray cell. It allows predicting the different phase-states of the cell from only a very few full-wave simulations. Demonstrations are first given for a passive cell where different geometrical parameters are varied. Then, the approach is generalized to a reconfigurable cell. Finally, a canonical reflectarray wit...
متن کاملA Complete Electrical Equivalent Circuit Model For Biological Cell
A theoretical ac impedance model of biological tissue has been proposed after studying a cellular membrane using X-ray diffraction technique [1], a metal/organic system using ac impedance spectroscopy [2] and reviewing two pieces of literature of similar topics [3,4]. This paper emphasizes ac impedance techniques which can be used to study any heterogeneous materials in order to develop a lumpe...
متن کاملAn equivalent circuit approach to organic solar cell modelling
In this paper, we present a simulation study for a newly prepared organic solar cell, based on a composite of poly (2-methoxy5-(20-ethylhexyloxy)-1, 4-phenylenevinylene (MEH-PPV) with [6, 6]-phenyl C60 butyric acid methyl ester (PCBM). Photo-current density vs. voltage (J–V) characteristics, for the cell, which were experimentally studied earlier, have been revisited here. The results indicated...
متن کاملOrigins of the Equivalent Circuit Concept: The Voltage-Source Equivalent
The theoretical foundations of linear circuit theory rest on Maxwell’s theory of electromagnetism. In its more applied form, circuit theory rests on the key concepts of Kirchoff’s Laws, impedance, Ohm’s Law (in its most general sense by encompassing impedances), and the Principle of Superposition. From this foundation, any linear circuit can be solved: Given a specification of all sources in th...
متن کاملOrigins of the Equivalent Circuit Concept: The Current-Source Equivalent
As described in my previous paper [1], the voltage-source equivalent was first derived by Hermann von Helmholtz (1821–1894) in a 1853 paper [2]. Exactly thirty years later in 1883, Léon Charles Thévenin (1857–1926) published the same result [3, 4] apparently unaware of Helmholtz’s work. The generality of the equivalent source network was not appreciated until forty-three years later. Then, in 1...
