Near-Field Interactions Between Light and Surface Plasmons of a Metal Slab
Kuo-Pin Chiu,Din-Ping Tsai 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.47 No.1
In this paper, we calculate the attenuated total reflection (ATR) spectra of Au, Ag and Sb thin metal slabs with different thicknesses on nanometer scale by using the transfer matrix method. The metal slab is surrounded by thin dielectric films, such as ZnS . SiO2 or glass. The resonance absorption of the incident light, i.e. when the ATR spectrum has a minimum value, in the metal slab is studied. The resonance is due to the excitation of surface plasmons (SPs) at the interfaces between the metal slab and its surrounding dielectrics. It is found that both the thickness of the metal slab and the surrounding dielectric will change the surface plasmon (SP) resonant position and strength.

Advanced Imaging of Nanometer-Scale Recorded Bits on Super-Resolution Near-Field Optical Disk
Pei Lin Yang,Din Ping Tsai,Cheng Wei Lin,Chih Ching Hsu,Pei Hsin Chang,Tsung Sheng Kao,Wei Chih Lin 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.47 No.1
An advanced imaging technique is demonstrated for fast, non-destructive and high resolution characterizations for nanometer-scale recorded bits on a super-resolution near-field optical disk (super-RENS). For the first time, an array of individual 100 nm recorded marks is imaged and studied by using the conductive-atomic force microscopy (C-AFM) method. Discussions also include comparisons of 300 nm, 200 nm and 100 nm recorded marks on both a super-RENS disk and a commercial DVD disk, and the image results are evidence of the high carrier-to-noise ratio (CNR) value on the super-RENS disk, even though the mark size has been shrunk to less than the diffraction limit.

It has been claimed that a negative efraction index could be measured in a slab-shaped twodimensional photonic crystal, which is constructed of a square array of dielectric rods. In our numerical experiments, a Gaussian pulse is applied to analyze the negative refraction, and a dipole source is used to check superlensing effect. Based on our results, the observation of the negative angle of refraction is due to the spread of the electromagnetic field, and the flow of the wave shows no evidence of negative refraction. Furthermore, if a dipole source propagates into the photonic crystal, a dipole image should be found on the other side of the crystal, because of the superlensing effect; unfortunately, the image never appeared in our simulations. In conclusion, a two-dimensionalphotonic crystal may not be treated as a left-handed material.

Surface Plasmon Resonance in Metallic Nanocylinder Array
Tai Chi Chu,Wei-Chih Liu,Din Ping Tsai 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.47 No.1
Localized surface plasmon resonances of noble-metal nanoparticles lead to high enhancements of local electromagnetic fields near the nanoparticle surface and play a key role in surface-enhanced Raman scattering, surface-enhanced fluorescence, near-field microscopy, and plasmonic devices. Recently, research results have shown that electromagnetic energy can transfer along a metallic nanoparticle chain because of coupled plasmon modes. In this paper, finite-difference time-domain method was used to study the surface plasmon resonances in coupled silver nanocylinder (nanoparticle) arrays and slab-like periodic modulation structures. From the far-field transmittance and reflectance, three different resonance modes were excited for the periodic nanocylinder arrays and only one resonance was excited for the periodic modulation structure. The near-field intensity distributions exhibited highly enhanced fields at the center of the gaps for nanoparticle arrays and at the caves of the periodic modulation structure.
