Omega transmission lines [PDF]
In this paper, we show how bi-anisotropic media with omega-type response can be realized using periodically loaded transmission lines. General conditions for the needed unit cell circuit block are derived. Also, an implementation is shown and analyzed.

Effect of electrical erosion on composite insulator core rod under acidic environment
Silicone rubber housings crack under the combined internal and external factors and expose the core rod. The exposed core rod deteriorates or breaks under electric fields and electrical current. Based on the main characteristics and mechanism of the core
