Abstract
A grid () for selective transmission of electromagnetic radiation and a method for manufacturing such grid is proposed. Therein, the grid () comprises a structural element with walls () comprising a plurality of particles () of a radiation-absorbing material wherein the particles () are sintered together such that pores () are present between neighboring particles (). The pores () are at least partially filled with a second solid material. The filling of the pores () 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.
