Abstract-This paper presents the estimation of emissivity of calibration load using discretized scattering simulation data in bistatic reflection measurement, and analyzes the effect of several measured parameters on emissivity of calibration load. In the analysis of the impact of measured parameters on emissivity, a new calibration target is designed to improve the accuracy of emissivity measurement. In this bistatic measurement, the scattering from calibration load is simulated by FDTD (Finite-Difference Time-Domain) method. Based on Kirchhoff's law, the emissivity of calibration load is estimated by the discretized scattering data composed of different scanning angle interval and sampling azimuth planes. By the studies of simulation results, the estimation accuracy of emissivity of calibration load can be improved by selected appropriate measured parameters in bistatic reflection measurement.

Abstract-Fundamental characteristics of a light-guiding metal line are revealed and discussed through the eigenmode analysis using the three-dimensional (3-D) imaginary-distance beam-propagation method (ID-BPM) based on the alternating-direction implicit scheme. For the present ID-BPM, the multiplication factor of the eigenmode is derived and the paper described how the present method works in the ID procedure. An efficient absorbing boundary condition is described, which is suitable for the eigenmode analysis using the ID-BPM. After confirming the effectiveness of the present method, the characteristics of the light-guiding line composed of a metal (Au) with a finite width and thickness on a substrate (SiO 2 ) are investigated. Numerical results for a metal thickness of 0.2 m show that the effective index and the propagation loss decrease as the metal width is reduced. It is shown that not only the higher order modes but also the first mode has a cutoff metal width. Near the cutoff width, the propagation loss of the first mode ( 10 dB/mm at a wavelength of 1.55 m) is less than those of the higher order modes. Finally, in order to reduce the propagation loss, a dielectric core was added under the metal line.Index Terms-Beam-propagation method (BPM), eigenmode analysis, imaginary-distance (ID) procedure, light-guiding metal line, surface plasmon-polaritons.

“…Equation (3) forms a parabolic-type equation so that the efficient BPM solvers developed so far can directly be applied to the solution of (3). We solve (3) by the Crank-Nicolson (CN) scheme with and without the ADIM [13], [15]. With the ADIM, the resultant FD equations are efficiently solved by the Thomas algorithm.…”

“…The TD-BPMs developed so far can roughly be di- vided into three classes, i.e., full-band (FB) [10], [19]- [21], wide-band (WB) [16]- [18], and narrow-band (NB) [8]- [15] TD-BPMs. The feature of the TD-BPM is that only the time-varying optical envelope is analyzed.…”
