For applications in dense wavelength-division-multiplexing (DWDM) systems, optical periodic filters with a rectangular spectral response are highly desirable to maximize system performance.
In this paper, optical periodic filters using a multi-reflector Gires Tournois resonator (MRGTR) in a Michelson interferometer (MI), are theoretically investigated.
We show that when the additional numerical dissipation is close to the subgrid-scale (SGS) dissipation of an explicit LES the overall accuracy of ILES is also comparable, indicating that periodic filtering can replace explicit SGS models.
An optimized non-periodic filter will remarkably improve the spectral efficiency of the STPV.
Uddin et al. reported a multi-periodic color filter, in which three different grating periods generate respectively the red, green, and blue colors for reflected TE-polarized light [9].
A periodic and asynchronous filter means that the filter parameters are s-periodic for a given operating mode, and its operating modes are unnecessary to be identical but form a periodic hidden Markov model together with the modes of the plant.
This paper is devoted to developing a periodic and asynchronous filter for periodic Markov jump systems.
In order to simplify the structures, Uddin et al. reported a single periodic tri-color filter, which was obtained by tuning the incident angles of TE polarization [13].
The paper describes the development of periodic structure mechanical filter (PSMF) that has the potential to reduce vibration transmission and sound radiation at resonances of the foundation in a two-degree-of-freedom (2dof) vibration isolation system by using the band gaps of the periodic structure.
Filtering methods are derived for designing linear periodic asymptotically stable filters with either a prescribed upper-bound on the l2-gain from the noise signals to the estimation error, in the H∞ case, or a guaranteed upper-bound on the average steady-state variance of the estimation error variance, for the guaranteed variance filtering, in spite of the parameter uncertainty.
