Abstract:
In this document, after defining biquaternions algebra, Poynting Theorem is derived in this algebra. Because of 8-component biquaternions containing 3-dimensional vector space and 4-dimensional quaternion space, we can examine many physical quantities in biquaternion algebra. Based on this information, the generalized field Maxwell Equations and Gauge Transformations is showed in non-comutative but associative biquaternion algebra in homogenous media. Then, Noether and Poynting Theorems are introduced in terms of biquaternionic differential operator equation and used for deriving equations in

Abstract:
Poynting's vector theorem P=ExH is one of the universal laws of physics that applies to electromagnetic fields in AC and DC circuits. A rigorous analysis of two arbitrary cases of DC and AC circuit electromagnetic fields shows that Poynting's law P=ExH applies to both station ary and time-varying electromagnetic fields. Keeping the generality, we analyze two simple cases of time-varying and stationary fields of a regular cylindrical wire carrying direct or alternating current where in both cases the electromagnetic energy flow calculations validate the hypothesis that the theorem of Po

Abstract:
Efforts to suggest a classical model for the hydrogen atom are discouraged by a conclusion, based on the principles of electrodynamics, that an accelerating charged particle necessarily radiates. In this paper, we re-examine the steps leading to this conclusion. We start with the relativistic expressions for energy and momentum of a particle and establish the relationship between special relativity and electrodynamics. The standard field expression and its relativistic transformations are then studied for a point charge source, represented by a delta function. In conventional Poynting’s theore

Abstract:
A criterion for determining the stability of solutions of Hill’s equation containing even periodic potential is developed based on Hill’s method of solution. In the special case of the Mathieu equation, the theorem is applied to generate stability maps that compares well with those obtained by existing methods. Finally, stability of Poynting oscillations of a rigid disk attached to a neo-Hookean rubber rod is briefly discussed.

Abstract:
A comprehensive and rigorous description of instantaneous balance of electromagnetic power defined as the derivative of energy with respect to time is offered by the Poynting's theorem. Such theorem is expressed as the sum of a series of volume integrals representing the volume densities of densities of different components of electromagnetic power and the power flow through the general surface surrounding the entire domain in which the Poynting's vector expresses the instantaneous power leaving the domain (the positive normal is the outward normal to the enclosing surface).

Abstract:
In this chapter the same basic topics are addressed as in the previous chapter, but now in the presence of matter. This greatly complicates the description of optical propagation and continues to be the primary topic of the remaining chapters. A formal structure is developed to handle absorption and scattering phenomena in general. The modeling of optical propagation is reduced to having to know the complex index of refraction of the medium. A macroscopic description represents the large-scale observable character of optical propagation. At this level, many models are phenomenological, but lea

Abstract:
Abstract In this chapter we begin our study of electromagnetic fields in materials. We first show how the fundamental Maxwell equations give rise to ‘smoothed’ Maxwell equations valid at macroscopic scales. To use these equations, however, we must have a model for the macroscopic charge and current densities. We introduce the polarization vector field P and the electric displacement vector field D for a dielectric and the magnetization M and the H field for magnetic material, and we write the Maxwell equations in terms of these quantities. The complexity of the materials is then described phen

Abstract:
Microwave heating is very popular and widely used for warming up foodstuffs quickly. However, non-uniform temperature distribution obtained from microwave heating is a major limiting factor for its application outside the food industry. The rapid decay of incident microwave and the potential existence of standing wave are responsible for non-uniform heating. Therefore, it is important to study the coupling between microwave propagation and energy transfer in the system to predict temperature distribution. In this paper, a closed-form analytical solution is presented to predict the temperature

The effects of doping level, polarization, and width of the vacuum gap on the overall radiative transfer were investigated.

With the energy saving concerns, microwave heating method becomes much attention in heating process of various applications. Depending on applicator geometry design, type of work load, and position in a microwave heating system, it can save energy 20% to 40% more than the energy consumed by a conventional heating method. However, it is difficult to achieve this energy saving for low dielectric constant workload that cannot perform as a self-dielectric resonator (DR) load.
