| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this study, we shall examine the asymptotic analysis method for the transient whispering gallery (WG) mode radiation field radiated from an end-aperture of a variable radius of concave conducting surface. We assume that the WG mode is excited by a high-frequency pulse source with a truncated Gaussian time variation. Comparisons with the reference solution obtained by the numerical integration of the inverse Fourier transform of the product of the frequency-domain UTD (uniform GTD) solution for the WG mode radiation field and the frequency spectrum of a pulse source reveal the validity of the proposed asymptotic analysis method. We shall also clarify the differences between the time-domain UTD solution proposed in the present study and the conventional asymptotic solution. | |
