Modeling magnetic nanoparticle dipole-dipole interactions inside living cells
Physical Review B, 2011Biomedical applications based on superparamagnetic nanoparticles injected in vivo may be affected by the cellular uptake of these nanoparticles. Living cells indeed capture and internalize nanoparticles, concentrating them into intracellular vesicles called lysosomes.

Controlling magnetic dipole transition with magnetic plasmonic structures
Optics Letters, 2011A plasmonic structure with double gold patches is proposed for enhancing the spontaneous emission of a magnetic dipole transition through a magnetic hot area. A Purcell factor of nearly 2000 can be obtained at optical frequencies together with a low sensitivity in spatial and spectral mismatches between the light emitter and the resonance mode.

AbstractA very compact antenna with magnetic dipole radiation properties is presented. It is horizontally polarized HP with low cross polarization level XPR, it has omnidirectional radiation with a very low ripple in the azimuth cut plane. With a compact design (quarter wavelength square) it is suitable for integration into small WLAN devices.

Magnetic field of a dipole and the dipole–dipole interaction
European Journal of Physics, 2007With a data-acquisition system and sensors commercially available, it is easy to determine magnetic fields produced by permanent magnets and to study the dipole–dipole interaction for different separations and angular positions of the magnets. For sufficiently large distances, the results confirm the 1/R3 law for the magnetic field and the 1/R4 law for
