Design of a dual band-pass filter using modified folded stepped-impedance resonators
(Institute of Electrical and Electronics Engineers, 2009)
A folded stepped impedance resonator (SIR) modified by adding an inner quasi-lumped SIR stub is used as the basic block of a new configuration of dual band-pass filter. The main advantage of the proposed filter is to allow ...

Wideband analytical equivalent circuit for coupled asymmetrical nonaligned slit arrays
(American Physical Society, 2017)
Microstructured metallic devices have been extensively studied because of their interesting properties for controlling the transmission, reflection, and absorption of electromagnetic waves. A very simple implementation is ...

Multi-band high-impedance surface absorbers with a single resistive sheet: Circuit theory model
(Institute of Electrical and Electronics Engineers, 2011)
We present a simple and efficient circuit model for the analysis of multi-band absorption characteristics of a stack of sub-wavelength grids (fishnets or patch arrays) in a layered environment with a single resistive sheet ...

Analytical theory of wave propagation through stacked fishnet metamaterials
(Optical Society of America, 2009)
This work analyzes the electromagnetic wave propagation through periodically stacked fishnets from zero frequency to the first Wood's anomaly. It is shown that, apart from Fabry-Perot resonances, these structures support ...

Efficient evaluation of reaction integrals in the EFIE analysis of planar layered structures with uniaxial anisotropy
(Institute of Electrical and Electronics Engineers, 2002)
This paper presents an efficient implementation of the electric-field integral-equation (EFIE) method to deal with planar anisotropic layered printed structures. A convenient treatment of the kernel of the integral equation ...

Left-handed-media simulation and transmission of EM waves in subwavelength split-ring-resonator-loaded metallic waveguides
(American Physical Society, 2002-10-28)
At microwave frequencies, hollow metallic waveguides behave in certain aspects as a “one-dimensional plasma.” This feature will be advantageously used for simulating the propagation of electromagnetic (EM) waves in left-handed ...

Equivalent circuits for conventional and extraordinary reflection in dipole arrays
(Institute of Electrical and Electronics Engineers, 2011)
This presents an equivalent transmission-line circuit that accounts for the scattering of a TE polarized plane wave that impinges obliquely on a periodic array of metallic patches sandwiched in a dielectric slab. The ...

Analytical circuit model for stacked slit gratings
(Institute of Electrical and Electronics Engineers, 2014)
This work presents a rigorous circuit model to compute the transmission/reflection properties of a finite number of stacked slit gratings printed on dielectric slabs of arbitrary thickness. A key aspect of the present ...

Experimental verification of extraordinary transmission without surface plasmons
(American Institute of Physics, 2009)
This letter provides an experimental demonstration of extraordinary transmission in a closed waveguide system loaded with an electrically small diaphragm. This is a situation where the standard surface plasmon polariton ...
