Aplikasi Aljabar Geometris Pada Teori Elektrodinamika Klasik

open access: yesJurnal Fourier, 2012
In this paper geometric algebra and its aplication in the theory of classical electrodynamic will  be studied. Geometric algebra provide many simplification and new insight in the theoretical formulation and physical aplication of theory.

The Impacts of Tropospheric Gravity Wave‐Generated MSTIDs on Skywaves at Mid‐latitude North American Sector Observed and Modeled Using SuperDARN HF Radars

open access: yesRadio Science, Volume 61, Issue 9, September 2026.
Abstract Trans‐ionospheric high frequency (HF: 3–30 MHz) response to atmospheric gravity waves (GWs) is studied in the middle‐latitude ionosphere in relation to thunderstorm activity. SuperDARN HF radar observations are compared against the model simulations to quantify the impact of GW‐generated medium‐scale traveling ionospheric disturbances (MSTID ...

Assessment of MR‐Induced Heating Effects in Four Common Veterinary Implants at 1.5 and 3.0 T: A Phantom Study

open access: yesVeterinary Radiology &Ultrasound, Volume 67, Issue 5, September 2026.
ABSTRACT Quantitative evaluation of implant‐related heating in magnetic resonance imaging (MRI) is well standardized in human medicine, whereas evidence in veterinary medicine remains scarce. To address this gap, we measured radiofrequency (RF)‐induced heating of four used veterinary implants under controlled conditions on clinical 3.0 and 1.5 T MRI ...

Photons and temporality in quantum electrodynamics [PDF]

open access: yes, 2008
The lowest order processes described within quantum electrodynamics are free from the problem with infinities in the theory, and can be dealt with disregarding the need for charge and mass renormalization.

Classical electrodynamics in a space with spin noncommutativity of coordinates

open access: yesPhysics Letters B, 2016
We propose a relativistic Lorentz-invariant spin-noncommutative algebra. Using the Weyl ordering of noncommutative position operators, we find a mapping from a space of commutative functions into space of noncommutative functions.

Quantum Plasmonic Dynamics Modeled via a Modified Langevin Noise Formalism: Numerical Studies of Single‐Photon Emission and Two‐Photon Interference

open access: yesNanophotonics, Volume 15, Issue 16, 26 August 2026.
Based on the modified Langevin noise formalism and BA‐MA theory, optimized computational formulations are demonstrated for quantum plasmonic simulations without explicit BA–MA mode construction. Plasmonic Hong‐Ou‐Mandel interference, g2, atomic population, and single‐photon probability amplitudes are efficiently analyzed, revealing directional single ...

Spin Three-Body Problem of Classical Electrodynamics with Radiation Terms (I) Derivation of Spin Equations

open access: yesResults in Nonlinear Analysis, 2021
In the present paper spin equations for three-body problem of classical electrodynamics are introduced. They should be considered jointly with 3-body equations of motion derived in a previous paper of the author.

A proposed measurement of optical orbital and spin angular momentum and its implications for photon angular momentum

open access: yesPhysics Letters B, 2018
The expression for the total angular momentum carried by a laser optical vortex beam, splits, in the paraxial approximation, into two terms which seem to represent orbital and spin angular momentum respectively.

The renormalization of charge and temporality in quantum electrodynamics [PDF]

open access: yes, 2008
In this article it is intended a closer look at the renormalization procedure used in quantum electrodynamics to cope with the divergent integrals that appear in higher-order calculations within the theory.

General Classical Electrodynamics [PDF]

open access: yes, 2016
Maxwell’s Classical Electrodynamics (MCED) suffers several inconsistencies: (1) the Lorentz force law of MCED violates Newton’s Third Law of Motion (N3LM) in case of stationary and divergent or convergent current distributions; (2) the general Jefimenko ...
