By computational optimization of air-void cavities in metallic substrates, weshow that the local density of states (LDOS) can reach within a factor of$\approx 10$ of recent theoretical upper limits, and within a factor $\approx4$ for the single-polarization LDOS, demonstrating that the theoretical limitsare nearly attainable. Optimizing the total LDOS results in a spontaneoussymmetry breaking where it is preferable to couple to a specific polarization.Moreover, simple shapes such as optimized cylinders attain nearly theperformance of complicated many-parameter optima, suggesting that only one ortwo key parameters matter in order to approach the theoretical LDOS bounds formetallic resonators.
