-----Original Message----- From: pagnu...@htdconnect.com BTW, an interesting paper illustrating how powerful these fields can get in nanocircuits is -
"Optical generation of intense ultrashort magnetic pulses at the nanoscale" http://arxiv.org/abs/1303.6072 The underlying suggestion, which we have heard before in a different context, being the major part of the Letts/Cravens effect - is that coherent electric fields at the nanoscale can produce multi-Tesla level magnetic fields at the focal point. This paper is using laser light, but there is a more interesting possibility for LENR which came up several times in discussions wrt the HotCat. The near-coherence (aka superradiance) which is to be expected in the IR due to very narrow range emission from silicon carbide could be one of the secrets of the HotCat. Even though the photons of Terahertz IR carry far less energy per photon than an optical laser, there are far more of them with hot SiC, and they do not need to be focused. The energy per photon is perhaps 100 times lower but the intensity of narrow spectrum radiation is much larger. This gives Rossi the desirable magnetic field gradient in surface plasmons without the need of laser coherency or focusing and it gives a high level of control.
