Ideal Magnetic Dipole Scattering. [PDF]
Physical Review Letters, 2017 We introduce the concept of tunable ideal magnetic dipole scattering, where a nonmagnetic nanoparticle scatters light as a pure magnetic dipole. High refractive index subwavelength nanoparticles usually support both electric and magnetic dipole responses.

Gyre-driven decay of the Earth's magnetic dipole. [PDF]
Nat Commun, 2016 Direct observations indicate that the magnitude of the Earth’s magnetic axial dipole has decreased over the past 175 years; it is now 9% weaker than it was in 1840.
