Abstract

A grid (1) for selective transmission of electromagnetic radiation and a method for manufacturing such grid is proposed. Therein, the grid (1) comprises a structural element with walls (3) comprising a plurality of particles (19) of a radiation-absorbing material wherein the particles (19) are sintered together such that pores (21) are present between neighboring particles (19). The pores (21) are at least partially filled with a second solid material. The filling of the pores (21) can be done by inserting the second material in a liquid, preferably molten form into the pores. The second material can be itself radiation-absorbing as well and may help to both, increase the mechanical stability of the grid and to enhance the radiation-absorbing properties.
