Summary
Can incoherent emission be optimized without an independent solve for every source?
Expresses emission as a trace and exploits low-rank structure.
Extends few-channel reciprocity approaches to objectives involving a continuum of directions.

Commentary
Efficiency depends on the rank needed to represent the particular source and measurement problem.
Shares the use of source correlations with coherence methods, but targets optimization of emitted power.
