Journal ArticleDOI
Improved form of backfire bifilar helix conical beam antenna
TL;DR: The backfire bifilar helix is often used as a vehicle satcom antenna, as it has a circularly polarized conical beam with azimuthal symmetry.
Development of an Undergraduate Multidisciplinary Engineering Project
David R. Smith,Jo Cole +1 more
TL;DR: The School of Engineering and Design Multidisciplinary Project (MDP) as mentioned in this paper was introduced in 2007 to provide first year undergraduate students with an opportunity to work together in multidisciplinary teams on a design and construction project.

General Theory on Artificial Metamaterials
TL;DR: In this article, a general theory of effective media is presented to establish the relationship between the local field responses on metamaterial structure and the macroscopical behaviors for artificial metammaterials composed of periodic resonant structures.
