Optimal Focusing for Monochromatic Scalar and Electromagnetic Waves
, 2010 For monochromatic solutions of D'Alembert's wave equation and Maxwell's equations, we obtain sharp bounds on the sup norm as a function of the far field energy. The extremizer in the scalar case is radial.

Maxwell’s equations in the Myers-Perry geometry
Journal of High Energy Physics, 2017 We demonstrate separability of the Maxwell’s equations in the Myers-Perry-(A)dS geometry and derive explicit solutions for various polarizations. Application of our construction to the four-dimensional Kerr black hole leads to a new ansatz for the ...
