Claim Text:
1. A tunable waveguide structure having a longitudinal extension and comprising a first inner wall having a first main surface and being electrically conducting, a second inner wall having a second main surface and being electrically conducting, a third inner wall having a third main surface and being electrically conducting, and a fourth inner wall having a fourth main surface and being electrically conducting, said first through fourth inner walls being mounted such that a rectangular cross-section is obtained for the waveguide structure where the first inner wall faces the second inner wall, the third inner wall faces the fourth inner wall, the length of the first inner wall is equal to a first length, the length of the second inner wall is equal to said first length, the length of the third inner wall is equal to a second length, and the length of the fourth inner wall is equal to said second length, wherein the tunable waveguide structure comprises at least one electrically controllable tuning device that is arranged for mounting at the first inner wall and/or the second inner wall, where the tuning device comprises a non-conducting substrate on which at least one row of Micro Electro Mechanical Systems, MEMS, cantilever switches is placed, wherein the switches are electrically openable and closable and are arranged to form an electrically conducting connection between the third inner wall and the fourth inner wall when the switches are closed, such that the switches constitute an artificial wall arranged to confine an electric field.
