Neo-Hertzian Wave Equation for Variable Detector Velocity
It has been argued previously [1-3] that a first-order invariant covering theory of Maxwell’s electromagnetism (EM) originally proposed by Hertz [4] provides not only a formally more comprehensive approach to EM description but one that is more competent to describe the weak-field (single photon) limit. This claim depends on a specific physical interpretation of the Galilean invariant formalism...
متن کاملThe Effect of Dynamic Permeability on Velocity and Intrinsic Attenuation of Compressional Waves in Sand
Stress waves contain useful information about the properties of porous materials; they can be recovered through different non-destructive testing methods such as crosswell, vertical seismic profile, borehole logging as well as sonic tests. In all these methods, it is crucial to assess the effects of frequency on wave attributes including velocity and intrinsic attenuation. The dependency of per...
متن کاملThe Biological Significanace of Water Structured with Non-hertzian Time Reversed Waves
Contemporary quantum physics has mathematically described and predicted the presence of a new kind of unified energy which underlies conventional transverse electromagnetic (EM) vectors. The concept of a subtle energy underlying EM fields was first introduced by Bohm and Aharonov 1 in describing quantum potentials as an implicate order "embedded in" our normal 3D space. It has recently been pro...
متن کاملHertzian impact: experimental study of the force pulse and resulting stress waves.
Ball impact has long been used as a repeatable source of stress waves in solids. The amplitude and frequency content of the waves are a function of the force-time history, or force pulse, that the ball imposes on the massive body. In this study, Glaser-type conical piezoelectric sensors are used to measure vibrations induced by a ball colliding with a massive plate. These measurements are compa...
متن کاملOn the Existence of Solitary Traveling Waves for Generalized Hertzian Chains
We consider the question of existence of “bell-shaped” (i.e. non-increasing for x > 0 and non-decreasing for x < 0) traveling waves for the strain variable of the generalized Hertzian model describing, in the special case of a p = 3/2 exponent, the dynamics of a granular chain. The proof of existence of such waves is based on the English and Pego [Proceedings of the AMS 133, 1763 (2005)] formul...
