Fireball ejection from a molten hot spot to air by localized microwaves.

Dusty Plasmoids Ejected from Silicon by Localized Microwaves - Reflection Analysis

This paper presents an experimental and theoretical investigation of plasmoids, in forms of fireballs and fire-columns, obtained by directing localized microwaves (~0.8 kW at 2.45 GHz) into a solid substrate (e.g. silicon) in a microwave cavity. The plasmoid is blown up from the hotspot created in the silicon substrate to the air atmosphere within the microwave cavity. The experimental diagnost...

Influence of Grating Parameters on the Field Enhancement of an Optical Antenna under Laser Irradiation

In this study, a new approach for simulation of electric field enhancement ofplane wave laser around optical antenna was used to convert free-propagating opticalradiation to localized energy. A tapered gold tip design as a novel geometry of opticalantenna is introduced and numerically analyzed based on particle swarm optimization(PSO) by solving the Maxwell equations wit...

Evidence for nanoparticles in microwave-generated fireballs observed by synchrotron x-ray scattering.

The small-angle x-ray scattering method has been applied to study fireballs ejected into the air from molten hot spots in borosilicate glass by localized microwaves [V. Dikhtyar and E. Jerby, Phys. Rev. Lett. 96 045002 (2006)10.1103/PhysRevLett.96.045002]. The fireball's particle size distribution, density, and decay rate in atmospheric pressure were measured. The results show that the fireball...

Drying Macadamia Nuts by Hot Air Combined with Microwaves as Compared to the Conventional Hot Air Process

Diamagnetic blob interaction model of TTauri variability

Assuming a diamagnetic interaction between a stellar-spot originated localized magnetic field and gas blobs in the accretion disk around a TTauri star, we show the possibility of ejection of such blobs out of the disk plane. Choosing the interaction radius and the magnetic field parameters in a suitable way gives rise to closed orbits for the ejected blobs. A stream of matter composed of such b...
