Comment on "electromagnetic resonances in individual and coupled split-ring resonators"
(American Institute of Physics, 2003)
Resonances appearing in split-ring resonators (SRR) were explained by the theory about the magnetoelectric coupling in the tensor polarizability of these particles. The relative strength of the resonances was explained ...

Full-wave analysis of a wide class of microstrip resonators fabricated on magnetized ferrites with arbitrarily oriented bias magnetic field
(Institute of Electrical and Electronics Engineers, 2002)
A numerical code has been developed for the full-wave determination of the resonant frequencies and quality factors of microstrip patches with right-angle corners of arbitrary shape in the case in which the substrate of ...

On the use of SDA for the analysis of boxed planar lines with complex media
(Institute of Electrical and Electronics Engineers, 2001)
This paper discusses the conditions under which the spectral-domain approach (SDA) can be applied to the analysis of boxed planar lines when complex materials (anisotropic dielectrics, ferrites, magnetoplasmons, chiral ...

COPAS: A New Algorithm for the Partial Input Encoding Problem
(Hindawi Publishing Corporation, 2002)
Frequently, the logic designer deals with functions with symbolic input variables. The binary encoding of such symbols should be chosen to optimize the final implementation. Conventionally, this input encoding (IE) problem ...

Near-field enhanced imaging by a magnetized ferrite slab
(American Institute of Physics, 2005)
This letter demonstrates the near-field imaging enhancement at microwave frequencies of two-dimensional sources by a ferrite slab magnetized to saturation. It is shown that this effect is based on the nonreciprocal ...

Operation limits for RTD-based MOBILE circuits
(IEEE, 2009-02)
Resonant-tunneling-diode (RTD)-based monostable-bistable logic element (MOBILE) circuits operate properly in a certain frequency range. They exhibit both a minimum operating frequency and a maximum one. From a design point ...

Fine cohesive powders in rotating drums: Transition from rigid-plastic flow to gas-fluidized regime
(American Physical Society, 2002)
We investigate the dynamics of fine cohesive powders inside rotating drums. We show that these powders may be fluidized due to entrapment of ambient gas, and we determine the onset of fluidization. Experimental measurements ...

Design of compact low-pass elliptic filters using double-sided MIC technology
(Institute of Electrical and Electronics Engineers, 2007)
A novel implementation of stepped-impedance low-pass elliptic filters is presented in this paper. The filters are based on the well-known technique of cascading high- and low-impedance sections to simulate the ladder LC ...

Fast full-wave analysis of multistrip transmission lines based on MPIE and complex image theory
(Institute of Electrical and Electronics Engineers, 2000)
The mixed-potential electric-field integral equation is used in conjunction with the Galerkin's method and complex image theory for analyzing a transmission line with multiple strips embedded in different layers of a ...

Aggregation and sedimentation in gas-fluidized beds of cohesive powders
(American Physical Society, 2001)
We present measurements on the settling velocity of gas-fluidized beds of fine cohesive powders. In the solidlike regime ~solid volume fraction f.fc) particles are static, sustained by enduring contacts. The settling is ...
