This paper updates earlier thoughts by the author on a putative propulsion system. The concept was based around static electromagnetic momentum, as expounded in the "Feynman Disk" and experimentally verified by Graham and Lahoz. That... more
Assuming the fundamental importance of division algebras, we introduced the division algebra of quaternions as a framework for description of four-dimensional space-time intervals. We derived the quaternion form of the Lorentz time... more
Receiving of remote sensed data's signals in urban space information reception centers is usually difficult, because of complex electromagnetic situation in cities and insufficient EMC. Traditional methods for digital... more
A tri-band bandpass filter using stub loaded resonator (SLR) and defected ground structure (DGS) resonator is proposed in this letter. The DGS resonator on the lower plane constructs the first pass-band, and the SLR on the upper plane... more
Faraday's discovery of electromagnetic induction transformed the world by providing the blueprint for the mass production of electricity and a new type of motor that replaced the steam engine as the main driving force of the global... more
This paper explores a class of non-linear constitutive relations for materials with memory in the framework of covariant macroscopic Maxwell theory. Based on earlier models for the response of hysteretic ferromagnetic materials to... more
We considered a muffin-tin periodic potential (-8 inside the spheres and zero outside). Using the augmented-plane-wave method we systematically studied the location of gaps for positive energy and for various values of 8 and the sphere... more
As far as we are concerned, the implementation of the finite differences in the time domain (FDTD) method requires, for the solutions of several practical problems in electromagnetism, a long process time and a large amount of memory,... more
The rapid growth of wireless communication technologies has caused public concerns regarding the biological effects of electromagnetic radiations on human health. Some early reports indicated a wide variety of non-thermal effects of... more
Autonomous systems present the future of wireless networks and applications. Systems that are able to go anywhere and be truly "autonomous" have a huge advantage over those dependent on finite... more
This paper lays out the mechanics of creation in the 3-spaces model of an electron-positron pair as a photon of energy 1.022 MeV or more is destabilized when grazing a heavy particle such as an atom's nucleus, thus converting a... more
Most of the electromagnetic problems can be reduced down to either integrating oscillatory integrals or summing up complex series. However, limits of the integrals and the series usually extend to infinity. In addition, they may be slowly... more
Introduction à la théorie électromagnétique initiale de Maxwell avec analyse plus approfondie conduisant à l'établissement au niveau subatomique d'une mécanique claire d'émission et d'absorption de photons électromagnétiques et de... more
The basic purpose of this study is to determine the effect of the Course of Teaching Practice on Prospective Science Teachers' (PST) Teaching Methods and Technical Knowledge as it relates to Electromagnetism. The study group of the... more

В работе показана возможность и необходимость распространения принципа движения электромагнитного поля на электродинамические процессы. На основе анализа известных парадоксов электромагнетизма также показано, что закон электромагнитной... more
Increase in use of power electronics in power system addressed power quality problems. Converters are widely used in industrial area for different application. They are non-linear devices and degrade power quality of system. In this... more
Burglar alarm was designed to protect our stuff or even ourselves from a burglar.
♣ To describe the divers aspects of the gravitational and the electromagnetic "actions-at-a-distance", classical physics has introduced the field concept: the gravitational and electromagnetic vector fields are defined as the entities... more
Nearly two years ago I proposed a CRT experiment to test the magnetic field of a solenoid, see Non-Lorentzian Magnetic force and Aharonov-Bohm effect in CRT, Blogspot, Word published June-27-2013. Since its consequence is great (see... more
This paper summarizes how a new approach to the Universe based on the existence of a "crystalline ether", which has recently been detailed in the third versions of two books [1], makes it possible to find a simple, unified and coherent... more
Electrons flow and Potential difference or voltage is conjunction of cause effect of electro motion force in electromagnetic induction. Increasing potential and reactivity of electro motion force can increase that cause effect... more
Graduate level physics curricula in many countries around the world, as well as senior-level undergraduate ones in some major institutions, include Classical Mechanics courses, mostly based on Goldstein's textbook masterpiece. During the... more
The existing rocket propulsion mechanism derives energy from rocket fuels. The rocket fuel is burnt inside a chamber and gas produced due to combustion is expelled out through a nozzle, which produces the upward thrust for rockets or... more
A superluminal quantum-vortex model of the electron and the positron is produced from a superluminal double-helix model of the photon during electron-positron pair production. The two oppositely-charged (with Q = ±e sqrt (2/α) = 16.6e)... more

A simple way of deriving Huygens' principle in electromagnetic and transmissionline theory is given without recourse to Green's functions and Green's formulas.
Oil spills severely pollute seas and coastal environments. Satellite remote sensing and in particular Synthetic Aperture Radar (SAR), is effective to observe them. The observation effectiveness is strictly related to the modeling... more
An electromagnetic model is developed for the analysis of the coaxial-to-rectangular waveguide transition of the end-launcher type. The model describes the coupling mechanism in terms of an excitation probe which is fed by a transmission... more
This paper gives an account of the Gestalt Aether Theory of gravity. Gestalt Aether Theory clearly establishes the connection between electromagnetism and gravity and is able to account for every known or observed property of gravity. It... more
Diodes are used to contain any excess of voltage , caused when a circuit has the power shut off , and a feedback current spike , jumps the gap of the on / off switch ! This is caused by a change in Polarity of the circuit , and the surge... more
In our previous article in reference [1], we were able to reformulate Maxwell's equations in a simplified and microscopic form. This article on the other hand is a follow-up of the aforementioned article but in this case it is shown that... more
