Perfect Reflection of Light by an Oscillating Dipole

Understand

We show theoretically that a directional dipole wave can be perfectly reflected by a single point-like oscillating dipole.

• Furthermore, we find that in the case of a strongly focused plane wave up to 85 % of the incident light can be reflected by the dipole.
• Our results hold for the full spectrum of the electromagnetic interactions and have immediate implications for achieving strong coupling between a single propagating photon and a single quantum emitter.
