Abstract
A pressure barrier comprising a window with a first side and a second side, a main section comprising a length, a first end, and a second end opposite the first end, a first gradient compression section adjacent to the first end of the main section, and a second gradient decompression section adjacent to the second end of the main section is described. A pressure difference can be formed between the first and second side of the window. The window can comprise a dielectric material, where an average dielectric constant of the gradient compression section increases toward the main section, and an average dielectric constant of the gradient decompression section decreases away from the main section. A microwave propagating in a propagation direction can enter the pressure barrier at the gradient compression section and exit the pressure barrier through the gradient decompression section.
