An assembly unit includes side plate having first coupling member on first side, second coupling member on second side, and third coupling member on each of third and fourth sides, top plate including fourth coupling member and top stud, and bottom plate including fifth coupling member and bottom stud. The first coupling member is engaged with the second coupling member of neighboring side plate. The fourth coupling member is engaged with the third coupling member. The fifth coupling member is engaged with the third coupling member. The first coupling member includes protrusion. The second coupling member includes groove. The protrusion is fitted into the groove of the neighboring side plate. The third coupling member includes thread. Each of the fourth and fifth coupling members includes thread. The fourth and fifth coupling members are engaged with the third coupling member in a screwed manner using the threads.

A metamaterial for an electromagnetic wave filter includes a substrate; and a film disposed on the substrate and having a set of slots arranged to form a rotationally symmetric pattern, which is patterned in an intaglio shape, or a set of structures arranged to form a rotationally symmetric pattern, which is patterned in an embossed shape, to control a transmission rate according to polarization of an electromagnetic wave incident on the film. The set of slots or the set of structures have an array angle that is determined such that the transmission rate and a reflectivity thereof have constant values according to the polarization of the electromagnetic wave incident on the film, and have a chloroplast molecular structure pattern in which the set of slots or the set of structures are arranged in pentagonal and hexagonal shapes.

An assembly unit includes a side plate having a plate shape and including a first coupling member on first side, a second coupling member on second side, and a third coupling member on each of third side and fourth side, a top plate having a plate shape and including a fourth coupling member on each side and a top stud on the top surface, and a bottom plate having a plate shape and including a fifth coupling member on each side and a bottom stud on the bottom surface. The first coupling member includes a protrusion. The second coupling member includes a groove. When the first coupling member of the side plate is engaged with the second coupling member of a neighboring side plate of the same type as the side plate, the protrusion of the side plate is fitted into the groove of the neighboring side plate.
