Since Yee's seminal work the finite-difference time-domain (FDTD) method has attracted tremendous interest for the investigation of electro-dynamic problems. One of the current applications is the simulation of metallic structures in the context of realizing optical components with dimensions smaller than the wavelength of light, often referred to as the field of plasmonics. This article provides an overview of the literature on the FDTD method with regard to the simulation of metallic frequency dispersion. Focus is laid on the modelling of the frequency dependent character of the dielectric function of metals. Two independent fitting algorithms are described and applied to describe the real and complex susceptibility function of metals. Dispersive models for nobel metals commonly employed in FDTD simulations are compared and their implementation in the FDTD method is presented.

“…However, ray-tracing method is not suitable for analyzing the field coverage of the wireless link in complicated environments, so full-wave method is used in such environments. The typical fullwave method used is the finite-difference time-domain (FDTD) method [5,6], which has been used in studying the wave propagation in the micro-cell of mobile communication [7], between different floors of buildings [8], and in indoor environment [9]. It has also been combined with raytracing method to study the effect of wall on the indoor field coverage [10][11][12].…”

Base-band involved integrative modeling method (BIMM) is proposed for studying the transmission characteristics and bit error rate of the wireless communication, in which the transmitting and receiving antennas, wave propagation environment, and the modulation and demodulation modules are modeled and simulated integratively. Comparing with the conventional wave propagation method used in prediction of field coverage, BIMM is capable of taking the interaction between antenna and environment into consideration, and can give the time-domain waveforms of signals in different places of the wireless link, including those in the base-band modules. Therefore, the distortion reason of signal and in what place it happens can be found, and the bit error rate of the wireless communication can be analyzed. The BIMM in this paper is implemented by finite-difference time-domain (FDTD) method and is applied to the wireless link of railway communication. The effect of the electric spark generated by the power supplying network of the express train on the transmitting property and bit error rate is analyzed.

“…Also, we have studied the received level of the electric field by presence of forest in WiMAX wireless communications and street walls in RFID systems [3][4][5][6]. In this paper, we consider an elliptic cylinder on the planar ground as a simple object and study the electromagnetic scattering analytically using field expansion in terms of Mathieu function.…”

Radio wave technologies using electromagnetic waves of microwaves and ultra-high frequencies have been rapidly developed for high bit rate wireless communications and RFID application in outdoor and indoor spaces. Signal detection evaluation is very important factor in these systems including several objects along propagation paths of urban streets and country suburb, and, in houses and building. In order to estimate scattering and interference fields in many environments, typical useful models for scattering objects are dielectric elliptic cylinders on the planar ground. Field intensity distributions of electromagnetic waves in these circumstances are studied by Mathieu function expansion with addition theorems. Incident and scattering fields are expanded by Mathieu function series and coefficients of series are derived by electromagnetic field continuity equations of boundary conditions on the elliptic cylinder and planar surface. Reflection and scattered fields by elliptic cylinders on planar ground are shown by these series coefficients, and also fields in shadow regions between dielectric elliptic cylinders and planar ground. Field intensities in the elliptic cylinder including resonance cases for particular frequencies are evaluated. Reflection and scattered fields are compared with computer simulation results derived by numerical calculation of the FDTD method. Based on these field calculations optimum system design of WiMAX wireless communications and RFID systems in outdoor and indoor space regions are investigated. Positions and locations of radiating and receiving antenna for RF stations and RF readers may be decided from field results of this theory.
