In a Conductor-Backed Coplanar Waveguide (CBCPW) structure, an effective dielectric constant of a parallel plate waveguide is higher than that of a Coplanar Waveguide (CPW), so that a parallel plate leakage is generated. To reduce the parallel plate leakage, the present invention provides air cavities, whose dielectric constant is low, in a multilayer circuit so that the effective dielectric constant of the parallel plate waveguide of the CBCPW structure can be lowered.

Provided is an electrochemical device comprising two types of separators having different energy to break, wherein the outermost electrode layer of the electrode assembly includes an active material non-coated cathode, an active material non-coated anode, and a separator (second separator) disposed between the cathode and anode and having relatively low energy to break compared to that of separators (first separator) in other electrode layers. Therefore, it is possible to remarkably improve safety of the battery by inducing primary short-circuiting in the outermost electrode layer of a battery, thus facilitating heat dissipation of the battery, upon application of external impact.

A twist beam is manufactured from a tube and has a shorter sectional perimeter in the “V” or “U” shape center section and a longer sectional perimeter at the beam ends. The present disclosure therefore proposes to use a tubular member having a predetermined length. The tubular member is deformed at the center section of the tube into a “V” or “U” shape and then expanded at both end portions. This structure is formed using a closed die internal pressure forming process such as hydro-forming or blow molding or the like. The ends of the tubular member may also have a substantially oval or rectangular section. The tubular member of the present disclosure may also be heat treated in the closed die internal forming process to achieve a higher material strength. In this manner, the twist beam of the present disclosure is optimized to used the smallest possible section along its entire length, thus has a substantially lower mass and can be manufactured using less material and therefore at a substantially lower cost.
