1. A method for filtering a fluid with a filter apparatus, the method comprising:
with the use of a first filter system, of the filter apparatus, that includes a first structural layer, a second structural layer, and a third structural layer:
passing said fluid along a first direction of a flow of said fluid through the first structural layer that is defined by a first array of first rods, the first rods extending substantially along a first axis, wherein immediately neighboring first rods are separated from one another by first gaps;
receiving the flow of said fluid through the first structural layer at the second structural layer defined by a second array of second rods that extend substantially along the first axis and that are substantially staggered with respect to the first rods, and transmitting the flow of said fluid through the second structural layer;
reducing pressure of the flow of said fluid by passing the flow through a third structural layer spatially separated from the second structural layer in the first direction;
and
irradiating the second array of second rods with radiation that has a working wavelength and that arrives at the third structural layer in a second direction.
