Open AccessReducing the Dispersion of Periodic Structures with Twist and Polar Glide Symmetries
In this article, a number of guiding structures are proposed which take advantage of higher symmetries to vastly reduce the dispersion. These higher symmetries are obtained by executing additional geometrical ...

Open AccessOmnidirectional surface wave cloak using an isotropic homogeneous dielectric coating
The field of transformation optics owes a lot of its fame to the concept of cloaking. While some experimental progress has been made towards free-space cloaking in three dimensions, the material properties req...

Open AccessRemoving singular refractive indices with sculpted surfaces
The advent of Transformation Optics established the link between geometry and material properties and has resulted in a degree of control over electromagnetic fields that was previously impossible. For waves c...
