	Abstract:It is shown that the Lorentz reciprocity theorem is inadequate toan antenna system with a transmitter and receiver. The correct methodshould be to apply the mutual energy theorem. In the mutual energytheorem, an receiver can send an advanced potential. The mutual energycurrent is a inner product of a retarded potential and an advancedpotential. It is shown that the energy current corresponding to the Poynting vector does not transfer any energy. That means the mutual energy is the only one which can transferthe energy in the free space. It is shown that the mutual energy hasthe property of the photon and wave. This explained that why lightlooks like wave and also particles. The concept of mutual energy currentcomposed of retarded potential and advanced potential also offersa re-explanation for the probability in quantum physics. As a applicationof this theory, the method how to transfer time-reversed or superluminal signal usingadvanced potential is introduced. The reason why a action and reactioncan be done in 0 time with remote distance is also discussed.

	Abstract:Antenna system with at least one receive antenna is studied. The resultsand explanations of the reciprocity theorem and the mutual energytheorem are compared. Both the reciprocity theorem and mutual energytheorem can obtained similar results for the directivity diagram ofreceive antenna, but the conditions of the theorems established aredifferent. The mutual energy theorem is established in lossless media,the reciprocity theorem is established in symmetric media. Since theempty space is lossless and symmetric media, hence in empty spaceboth theorems are established. The explanations of the two theoriesare quite different. In the reciprocity theorem both transmitter andreceiver send retarded potentials. In the mutual energy theorem thetransmitter sends retarded potential and the receiver sends advancedpotential. This article studies the case where the media is lossy.Assume the media is still symmetric, hence the reciprocity theorem still established.The same result can be obtained by the reciprocity theorem comparedto the case where the media is lossless. For the mutual energy theoremit is not established in lossy media. However it can be extended tolossy media with a energy lossy item. From mutual energy theorem wecan obtained a correct result that the energy sends out by the transmitterequals to the energy loss on the media pluses the received energyof the receiver. Hence the extended mutual energy theorem can offercorrect result and the reciprocity theorem cannot. The result of this articlecan be further tested by a transmitter and receiver antenna in saltwater. If the mutual energy theorem wins that is not only offer amethod for antenna calculation in lossy media, but also further supportsthe absorber theory of Wheeler and Feynman, and the transactionalinterpretation for quantum physics and hence is very meaningful.

	Abstract:Ideal dielectrics can experience electromagnetic force although there are no real currents, charges and losses in them. Based on equivalence principle, we consider the electromagnetic force as the results of interaction among the electromagnetic waves, equivalent electric currents and magnetic currents. Our analysis shows that Minkowski form of electromagnetic momentum is supported by equivalence principle.

	4. Field Distribution in a Coaxial Electrostatic System with Sinusoidally Rippled Wall

	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:A coaxial electrostatic system is studied, where the inside surface of the outer conductor is corrugated with sinusoidal ripples and connected to a negative voltage while outside surface of the inner rod is smooth and grounded. The electrostatic potential is governed by a 2-dimensional Laplace equation in a cylindrical coordinates system with sinusoidal-ripples boundary conditions. By employing separation of variables, analytical solution of the field is derived in detail. Excellent agreement between the analytical formula and the CSTsimulation is confirmed. As an important application, it can be expected to play a role of the electrostatic wiggler in a free-electron laser.

	Abstract:Following a previous proposition of quaternity spacetime for electronic orbitals in neon shell, this paper describes the geometrical course each electron takes as it oscillates harmonically within a certain quaternity space dimension and provides the concrete connections between geometries and trigonometric wavefunctions that observe Pythagorean theorem. By integrating four quaternity space dimensions with conventional Cartesian coordinate systems in calculus, we explain electronic motions by the Maxwell equation and general Stokes theorem from the principles of rotation operation and space and time symmetry. Altogether with the previous reports, we have effectively established quaternity spacetime as a successful theory in elucidating the orbital shapes and motions of electrons within inert atoms such as helium and neon. We point out once again that 2px, 2py, and 2pz orbitals have different geometrical shapes as well as orthogonal orientations, contrary to the traditional 2p orbital model.

	Abstract:In this paper, the authors present the transmission line (TL) realization of one-dimensional subwavelength resonator formed by a pair of conventional right-handed material (RHM) and left-handed material (LHM). In such a resonator, a novel resonant mode with the resonant frequency depending on the length ratio of the RH/LH TL sections occurs as a consequence of the full phase compensation due to the backward wave in the LH TL section. The theoretical circuit-model analyses are supported by simulation and experimental evidence on resonators with different RH/LH length ratios.
