We derive from first principles an accurate homogenized description of periodic metamaterials made of magnetodielectric inclusions, highlighting and overcoming relevant limitations of standard…
Guided modes in a waveguide filled with a pair of single-negative (SNG), double-negative (DNG), and/or double-positive (DPS) layers

Here we present the results of our theoretical analysis for guided modes in parallel-plate waveguides filled with pairs of parallel layers made of any two of the following materials: (1) a material…
Magnetless Microwave Circulators Based on Spatiotemporally Modulated Rings of Coupled Resonators

Nonreciprocal components are ubiquitous in electronic and optical systems. To date, the use of magneto-optical materials has been the prevailing method to achieve nonreciprocity. However,…
Magnetic-free non-reciprocity and isolation based on parametrically modulated coupled-resonator loops
- N. A. Estep, D. Sounas, J. Soric, A. Alú
- Physics
