  • triple wavelength infrared plasmonic thermal emitter using hybrid dielectric materials in periodic arrangement
    Applied Physics Letters, 2016
    Co-Authors: Weilun Huang, Huihsin Hsiao, Ming Ru Tang, Sichen Lee
    Abstract:

    This paper presents a triple-wavelength infrared plasmonic thermal emitter using a periodic arrangement of hybrid dielectric materials within a tri-layer metal/dielectric/metal structure. The proposed arrangement makes it possible to sustain multiple resonance of localized surface plasmons (LSP), thereby providing an additional degree of freedom by which to vary the resonant wavelengths in the medium infrared region. Variations in the effective refractive index due to the different modal distribution within dielectric gratings results in multiple LSP resonances, and the resonant wavelengths can be easily tuned by altering the compositions of hybrid dielectric materials. The measured dispersion Relation Diagram and the finite difference time domain simulation indicated that the resonances were localized. They also indicate that the magnetic fields generated by the multiple LSP modes exhibit distribution patterns similar to that of a standing wave in the periodic arrangement of the hybrid dielectric layer, ...

  • double wavelength infrared emission by localized surface plasmonic thermal emitter
    Applied Physics Letters, 2014
    Co-Authors: Hunghsin Chen, Huihsin Hsiao, Hungchun Chang, Weilun Huang, Sichen Lee
    Abstract:

    A double wavelength infrared emission by plasmonic thermal emitter using stacked Au/SiO2/Au/SiO2/Au structure was investigated. The effective refractive index of sandwiched SiO2 is higher than normal value due to the coupling of surface plasmons at the top and bottom Au/SiO2 interfaces. Two different localized surface plasmon modes were excited with the same metal width, but different SiO2 layer thicknesses in top and bottom Au/SiO2/Au tri-layer structures. The measured dispersion Relation Diagram and simulation demonstrated that the resonances were localized resonance and the distribution of magnetic field was concentrated at the central SiO2 layer between two Au layers.

  • the spectral clustering based on the most similar Relation Diagram
    Advanced Materials Research, 2011
    Co-Authors: Min Zhu, Ya Ruo Jiang, Yu Shan Bai
    Abstract:

    In this paper we present a spectral clustering method based on the MSRD (Most Similar Relation Diagram). The feature of this method is that both the constructing of the adjacency matrix and the clustering are achieved by spectral algorithm. Experiment on an artificial datasets demonstrate that our method can generate balanced partition and detect the manifold clusters no matter the unnormalized or normalized Laplassian is used and can generate partitions with different features if different MSRD is used. Experiments on some real datasets proved that our method is valid and effective.

  • the clustering algorithm based on the most similar Relation Diagram
    International Conference on Computer Science Environment Ecoinformatics and Education, 2011
    Co-Authors: Min Zhu, Ya Ruo Jiang, Yu Shan Bai
    Abstract:

    The MSRD (Most Similar Relation Diagram) of a dataset is a weighted undirected graph constructed from an initial dataset. In the MSRD, each datum represented by a vertex, is connected with its MSD (Most Similar Data), and each MSRG (Most Similar Relation Group), represented by a sub-graph, is connected with its MSG (most similar group)through connecting the most similar pairs of data between the two sub-graph. The clustering algorithm based on the MSRD involves two stages: constructing the MSRD of the dataset and cutting the Diagram into sub-graphs (clusters). In this paper, we developed a package of methods for the later stage and applied them to some synthesized and real datasets. The performance verified the validity of these methods and demonstrated that the MSRD based clustering is a universal and rich algorithm.

  • the clustering methods based on the most similar Relation Diagram
    2011
    Co-Authors: Yu Shan Bai, Min Zhu
    Abstract:

    The MSRD (Most Similar Relation Diagram) of a dataset is a Diagram in which each datum is linked to its MSD (Most Similar Data) and each MSRG (Most Similar Relation Group) is linked to its MSG (Most Similar Group). In essence, the MSRD of a dataset is the visualization of the most similar Relations of the data. A clustering method based on the MSRD usually includes two stages: drawing the MSRD of the dataset and selecting some links in the MSRD to cut off. In this paper, we present a package of methods for the later stage and prove that the clustering based on the MSRD can detect both the spherical and non-spherical clusters simultaneously and has the capacity to distinguish the linearly inseparable clusters in high dimensional datasets.

  • a clustering method based on the most similar Relation Diagram of datasets
    Granular Computing, 2010
    Co-Authors: Yu Shan Bai
    Abstract:

    In this paper we present a novel clustering analysis method based on the Most Similar Relation Diagram (MSRD). MSRD is a Diagram in which each datum of a dataset is linked to its most similar data. By cutting off some links in the Diagram a certain number of clusters are formed. A compare of the MSRD method with hierarchical method is implemented. Clustering experiences using MSRD were done and the results demonstrated the validity of the method.
