Abstract-A new design of microwave band pass filter design is presented using metamaterial-inspired Epsilon Near Zero (ENZ) and Mu Near Zero (MNZ) behaviors. These filters are based on waveguide technology. The proposed structure allows us to reduce the number of tunnels normally used for passband filter design by reducing its size. It is also incorporated the half mode concept to the tunnels leading a greater miniaturization. Two Chebyshev filters with two and fourpoles were designed, fabricated and measured showing good agreement between simulated and experimental results.

“…The ENZ-based phenomena can either be realized using the metamaterials or through the narrow waveguide channels [22]- [25]. It has recently been shown that by using the property of the ENZ structure, the sensitivity of planar dielectric sensors can be substantially improved in comparison to other conventional SIW sensors [24].…”

A novel planar multilayered epsilon-near-zero (ENZ) tunnel sensor based on fully laminated surface integrated waveguide (SIW) technology is proposed for the microwave measurement of dispersive materials. The proposed sensor is designed and optimized using parametric analysis to obtain the multilayered ENZ tunnel dimensions. It is observed that the width of the upper tunnel of the designed two-tunnel sensor should be at least half of the SIW width of the actual SIW structure for the multiband operation. The complex permittivity measurement using the proposed sensor is possible at two frequencies with a single set of measurement data. The proposed method is based on perturbation of the squeezed electric field having constant magnitude and high intensity inside the multilayered ENZ tunnel, which eventually increases the sensitivity of the proposed sensor. The sensitivity and accuracy of the proposed sensor are tested using both the simulated and the experimented data. It is found that the proposed sensor is highly sensitive, and typically demonstrates 6% error under ideal conditions, thus making it a good candidate for the microwave measurement of dispersive materials.Index Terms-Cavity perturbation methods, dispersive materials, epsilon-near-zero (ENZ), microwave sensors, permittivity measurement, substrate integrated waveguide (SIW). 0018-9480

“…Most NZ structures proposed so far exploit behaviour of the TE10 propagation mode around its cut-off [5][6][7] which limits their application in planar circuits. Nevertheless, in [8][9] it has been recently demonstrated that NZ propagation can also be achieved in quasi-TEM structures, i.e.…”

In this paper we present a new class of dual-band filters based on near-zero propagation -a new paradigm emerging from recent developments of metamaterials. By using two different metamaterial unit cells and by properly coupling them to a microstrip host, permittivity-and permeability-nearzero propagation is achieved at two different frequencies, thus allowing the design of dual-band filters with arbitrary positioned passbands. At the same time, due to specific properties of NZ propagation, such filters will exhibit low insertion loss and good selectivity, as well as a reduced variation of group delay in comparison to the conventional solutions.
