An algorithm is introduced for generating frequency selective surfaces (FSSs) capable of
conforming to any curvature while maintaining the proper size, shape, and spacing of the …

Gradient refractive index (GRIN) materials are of interest for various applications where
transformation optic principles can be applied to the design of improved photonic and …

Spatial transforms are a popular technique for designing periodic structures that are
macroscopically inhomogeneous. The structures are often required to be anisotropic …

For the first time, a fully 3-D electric circuit was modeled in a 3-D environment and
manufactured via an automated hybrid direct-write 3-D printing process. The implications …

We present the Bio-Matched Horn antenna: a novel 1.773 cm 3 on-body antenna for very
low-loss communication with wireless implants across the 1-9 GHz bandwidth. To achieve …

Abstract 3D printing is a versatile fabrication method that offers the potential to realize
complex 3D devices with metamaterial characteristics in a single process directly from a …

The finite-difference frequency-domain (FDFD) method is a very simple and powerful
approach for rigorous analysis of electromagnetic structures. It may be the simplest of all …

This chapter introduces the tools and methodologies that can be used to engineer the
