One of the main properties of such structures is coherentre-reflections of the electromagnetic waves from the interfacesof the layers of the structure. That results in the collectivewave contributions and gives rise to various electromagneticeffects. We explore both frequency and radial dependencesof the field radiation and have found that in the area ofthe frequency resonances the spherical structure can confinethe electromagnetic fields. Our approach is based on thedyadic Green\'s function technique, which provides advancedapproximation for dynamical effects in a multilayered sphere.In a system with a few numbers of layers the electromagneticeffects due to the wave re-reflections cannot be appreciated.However our numerical approach has allowed us to apply thedyadic Green\'s function technique to multilayered spheres withany structure of the solid layers. This allows us to evaluate thetotal contribution of various field states in a multilayered spherein the unified framework. We have applied such a technique toa periodic and a quasiperiodic spherical structure. We found thatthe frequency spectrum of radiation consists of series of narrowand well separated peaks. In the band of such peaks the greatpart of the field energy is located in the stack\'s structure andpractically does not leave the sphere. A weak random deviationthe thicknesses of spherical layers on a periodic case is alsodiscussed. Such a theory can be useful to study the peculiarityof the spectrum of internal source radiated from Earth to asurrounding space.

In order to give thepossible explanation we link mentioned phenomena with amodification of the parameters of the ionosphere (such asdensity and the temperature), which is regularly detected duringsatellite observations over EQ preparation areas (DEMETERProject). Namely, the both fundamental mechanisms of thelithosphere-atmosphere-ionosphere coupling (i.e. coupling throwthe changes in the atmospheric electricity produced as result ofintegrated ionization from the increased radon emanation, andthe conversion of atmospheric acoustic gravity waves (AGW) andinternal gravity (IGW) in the lower ionosphere) can lead to themodulation of the ionosphere parameters, creating transparencyof the ionosphere for a passage of the Alfvén waves, which gofrom the magnetosphere to the Earth surface.We have calculated the efficiency of the modulation of theAlfvén wave at frequencies f = 0.1 – 10 Hz, which passes fromthe magnetosphere (z > 600 km) to the ionosphere and, the to theEarth´s surface and the lithosphere. The set of equations for theelectric field components Ex,y has been solved numerically. Theboundary conditions are as follows. At z = 800 km the amplitudeof the downgoing Alfvén wave is assumed as constant (the fieldof the Alfvén resonator), at z = -30 km (in the deep lithosphere)Ex,y = 0. The conductivity of the lithosphere vary between 10^3– 10^5 s-1. It has been obtained that the 20% modulation of theconcentration of the ion and electron concentrations at the heightsz = 200 km can lead to the same (or higher) modulation of theamplitude of the variable magnetic field at the Earth´s surface (z= 0) at f = 0.1 – 10 Hz. Moreover, the effect depends weakly onthe conductivity of the lithosphere. Therefore, an influence of thecoupling mechanisms on the F-layer of the ionosphere could leadto observable effects at the Earth´s surface.FE-3ENERGÍA BALSFIER: PROPUESTA,ANÁLISIS Y DISCUSIÓNTrigo Huesca AlfonsoUniversidad Nacional Autónoma de Méxicobalsfier@gmail.comSe presenta la propuesta, análisis y discusión de la energíaBalsfier, bajo la premisa de hacer confluir en un mismo paradigmalas teorias de Newton y Einstein, lo cual consiste en empatar enlas generalidades los conceptos de ambas teorías, de maneraque empleando las leyes Newtonianas para fabricar instrumentosde medición, se realicen mediciones de parámetros relativos a lateoría de Einstein.Se propone la base teórica para que los instrumentos deregistro tipo Ayax registren la perturbación en forma de ondaproducida por el cúmulo de masas que deforman el espaciotiempo en una línea definida y constante sobre un puntode registro en la Tierra, con tanta multiplicidad como seatécnicamente posible.Esto equivale a captar la onda resultante generada por muchasotras que le preceden y dan origen.Esta “onda” resultante no es una onda propiamente dicha, sinoun efecto de distorsión del continuo espacio-tiempo. Sin embargo,debido a la dualidad corpúsculo-onda operante en el Universo esposible tratar matemáticamente dichas distorsiones dándoles lacalidad de onda.Una vez implementadas los estudios propuestos se podrádefinir la capacidad teórica de aprovechar la energía primigeniadel Universo denominada Balsfier, cuyas característicasprincipales son la continuidad y permanencia.30
