Medvedev modeled wave diffraction off a circular reflecting region with radially varying index of refraction outside of it to better understand the Crab Nebula’s zebra pattern.

It contains a pulsar, designated PSR J1811−1925, and a pulsar wind nebula. The PWN in G11.2−0.3 is powered by PSR J1811−1925, which is located near the SNR's shell.
