Ultra-Small Bent Meta-Waveguide Filters

Maliheh Khatibi Moghaddam, Romain Christophe Rémy Fleury

This paper demonstrates the capability of locally resonant metamaterials (LRMs) for creating compact metallic waveguide E- and H-bends, which are simultaneously working as bandpass filters. For creating these bent meta-filters, we use composite pin-pipe wa ...

Ultra-Compact Ka-band Metamaterial Waveguide Filters, Fabricated by Lost-Wax Casting

Maliheh Khatibi Moghaddam, Romain Christophe Rémy Fleury

This paper proposes a novel technique for the design of miniaturized Ka-band filters based on locally resonant metamaterials (LRMs), which are fabricated monolithically using lost wax casting. We implement ultra-small metamaterial filters by exploiting a n ...

Subwavelength Metawaveguide Filters and Metaports

Maliheh Khatibi Moghaddam, Romain Christophe Rémy Fleury

This paper proposes an alternative technique for the design of miniaturized waveguide filters based on locally resonant metamaterials (LRMs). We implement ultrasmall metamaterial filters (metafilters) by exploiting a subwavelength (sub-λ) guiding mechanism ...

Miniaturized Metamaterial Filters Compatible with Standard Waveguide Technology

Maliheh Khatibi Moghaddam, Romain Christophe Rémy Fleury

In this paper, we study the behavior of miniaturized high-order waveguide filters, constructed by loading a hollow metallic waveguide with resonant pins, to form a locally-resonant metamaterial. Such composite pin-pipe structure supports a guided-mode with ...

A Subwavelength Microwave Bandpass Filter Based on a Chiral Waveguide

Maliheh Khatibi Moghaddam, Romain Christophe Rémy Fleury

Wave manipulation at a subwavelength scale has recently attracted significant interest, especially for low-frequency wave propagation, from acoustic to microwave devices. Recently, a few methods achieving subwavelength routing using locally resonant metama ...

Slow light engineering in resonant photonic crystal line-defect waveguides

Maliheh Khatibi Moghaddam, Romain Christophe Rémy Fleury

Slow light plays an outstanding role in a wide variety of optical applications, from quantum information to optical processing. While slow optical guiding in photonic crystal waveguides is typically based on Bragg band gaps occurring in non-resonant photon ...
