1. An electromagnetic apparatus, comprising:
- a focusing structure oriented to transmit output electromagnetic energy and having a nominal depth of field for input electromagnetic energy; and
a field-adjusting structure disposed to transmit the input electromagnetic energy and having electromagnetic parameters that provide an extended depth of field for the input electromagnetic energy greater than the nominal depth of field, the electromagnetic parameters including;
axial electromagnetic parameters; and
transverse electromagnetic parameters that inversely correspond to the axial electromagnetic parameters.

Abstract
Apparatus, methods, and systems provide emitting, field-adjusting, and focusing of electromagnetic energy. In some approaches the field-adjusting includes providing an extended depth of field greater than a nominal depth of field. In some approaches the field-adjusting includes field-adjusting with a transformation medium, where the transformation medium may include an artificially-structured material such as a metamaterial.
