It is suggested that where possible fundamental concepts and theories be presented from a historical perspective in undergraduate engineering education. Apart from being fairer to the contributions of the several researchers whose works often significantly contribute to a later-and much-acclaimed theory, such an approach can also be employed to(More)
The displacement-current concept introduced by James Clerk Maxwell is generally acknowledged as one of the most innovative concepts ever introduced in the development of physical science. It was through this that he was led to the discovery of his electromagnetic theory of light. While this concept and its development have received much admiration in the(More)
The world is facing an apparently increasing dose of violence. Obviously, there cannot be a simple solution to this complex problem. But at the same time it may be appreciated that, in the interests of humanity, a solution must be pursued in every possible way by everyone. This article is concerned with what one could possibly do at the academic level.(More)
A simple square loop printed antenna fed by a coplanar waveguide (CPW) is proposed. Considering a return loss criterion of better than 9.5 dB, the antenna operates in two frequency bands: 1.73–2.50 GHz and 3.44–3.87 GHz. These bands represent 36.4% and 11.8% impedance bandwidths respectively. A parametric study has also been carried out by(More)
The dynamical theory of electromagnetic fields was presented by James Clerk Maxwell in 1864 [1]. A more rigorous treatment of this was published later in 1873 as treaties where he used Cartesian coordinate system developed by Rene Des Cartes [2]. The theoretical foundations put forward by Maxwell have remained almost same over a period of more than 150(More)
