Secondary solitary wave formation in systems with generalized Hertz interactions.
We consider a chain of monodisperse elastic grains of radius R where the grains are barely in contact. The grains repel upon contact via the Hertz-type potential, V proportional to delta(n), n > 2, where delta > or = 0, is the grain-grain overlap, delta identical with 2R-(u(i+1)-u(i)), where u(i) denotes the displacement of grain i from its original equilibrium position. This being a computatio...
متن کاملMicrophotonic Components for a Mm-wave Receiver
A new microphotonic mm-wave receiver architecture with direct electrical-to-optical conversion is presented. The receiver uses high-Q RF and microphotonic electro-optic resonator components which are operated in simultaneous resonance. Initial results demonstrating modulation of an optical carrier at RF in the mm-wave range are reported .
متن کاملWave equation receiver deghosting: a provocative example
Here, we discuss a technique based on the wave equation that accomplishes up/down wavefield separation based on a single measurement that does not rely on the spectral ghost model and does not rely on statistical or other means of estimating missing frequencies. While it is a distinct advantage to record multiple measurements, such systems are limited in availability and, moreover, significant ...
متن کاملSolitary wave dynamics in generalized Hertz chains: an improved solution of the equation of motion.
The equation of motion for a bead in a chain of uncompressed elastic beads in contact that interact via the potential V(delta) approximately delta( n), n>2, delta being overlap, supports solitary waves and does not accommodate sound propagation [V. Nesterenko, J. Appl. Mech. Tech. Phys. 5, 733 (1983)]. We present an iteratively exact solution to describe the solitary wave as a function of mater...
متن کاملConcerning Hertz’ photoelectric effect
Experimental evidence of the photoelectric effect goes back to H. Hertz. It occurred during the famous confirmation experiments of the Maxwellian theory. It is commonly held however that it cannot be explained in the framework of that theory. We are calling attention to some aspects linked with the interpretation of that effect on which, in our opinion, it is worth-
