Electromagnetic radiation (EM radiation or EMR) is the radiant energy released by certain electromagnetic processes. Visible light is one type of electromagnetic radiation; other familiar forms are invisible electromagnetic radiations, such as radio waves, infrared light and X rays.
Electromagnetic waves are produced whenever charged particles are accelerated, and these waves can subsequently interact with any charged particles. EM waves carry energy, momentum and angular momentum away from their source particle and can impart those quantities to matter with which they interact. Quanta of EM waves are called photons, which are massless, but they are still affected by gravity. Electromagnetic radiation is associated with those EM waves that are free to propagate themselves ("radiate") without the continuing influence of the moving charges that produced them, because they have achieved sufficient distance from those charges. Thus, EMR is sometimes referred to as the far field. In this language, the near field refers to EM fields near the charges and current that directly produced them, specifically, electromagnetic induction and electrostatic induction phenomena.

XFdtd's schematic editor is a novel electromagnetic simulation tool that combines matching network analysis with full-wave results, making it ideal for complex antenna design applications involving�multi-state and multi-port aperture or impedance tuners and corporate feed networks with digital phase shifters.
Scientists say that the reason we are unable to see or detect this invisible matter is that it does not interact with electromagnetic forces — things like visible light, X-ray or radio waves.Advertisement ... It can’t interact with light or electromagnetism.
Based on electromagnetic wave resonance under deterministic finite precision computation, taking the form Q=σ(T4A−T4B), (1) ... Is radiative heat transfer carried by electromagnetic waves or particles/photons? An answer that it is both is no good ... waves instead of particle statistics.
