An UWB Hemispherical Vivaldi Array
Carl Pfeiffer, Jeffrey Massman
We report the first conformal ultra-wide band (UWB) array on a doubly curved surface for wide angle electronic scanning. We use a quadrilateral mesh as the basis for systematically…
3D Printed Metallic Dual-Polarized Vivaldi Arrays on Square and Triangular Lattices
Carl Pfeiffer, Jeffrey Massman, Thomas Steffen
We report the first Vivaldi arrays monolithically fabricated exclusively using commercial, low-cost, 3D metal printing (direct metal laser sintering). Furthermore, we developed one…
Free-Space Wide-Aperture Sheet-Isolator Based on a Multilayered Resonant Cavity
R. Kononchuk, C. Pfeiffer, I. Anisimov +3
We introduce the first conceptual design of a free-space thin-sheet isolator with unlimited aperture and the possibility of a broadband omnidirectional rejection of the backward pr…
Accelerating Light with Metasurfaces
Meredith Henstridge, Carl Pfeiffer, Di Wang +4
It has been recently shown that especially engineered light beams have the remarkable ability to propagate along curved trajectories in vacuum. Current methods for generating accel…
Fundamental Efficiency Limits for Small Metallic Antennas
Carl Pfeiffer
Both the radiation efficiency and bandwidth of electrically small antennas are dramatically reduced as the size decreases. Fundamental limitations on the bandwidth of small antenna…
Bianisotropic Metasurfaces: Ultra-thin Surfaces for Complete Control of Electromagnetic Wavefronts
Carl Pfeiffer, Anthony Grbic
Complete control of electromagnetic fields requires particles that exhibit bianisotropic constituent parameters (i.e. permittivity, permeability, and chirality). Here, methods to a…
