| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Orbital-Angular-Momentum(OAM) is attracting attention in terms of a novel multiplexing method. Multiplexing in OAM communication exploits orthogonality of the OAM wave which is a electromagnetic field possessing OAM. Induced currents for multiple expansion orders are analyzed with generalized Z-matrices, and optimum combinations for the port azimuths are found for short- and long-range OAM communication. Four-value multiplexing characteristics are estimated by simulation and measurement with loop arrays for port azimuths customized for short-range communication. The simulated and measured transmission isolations were more than 25.4dB and 23.6dB, respectively, for the distance of 10mm between the transmitting and receiving arrays. The measured isolation is as much as 9.2dB higher than the conventional arrays for identical port azimuths. With paraboloids and arrays optimized for long-range communication, 4-value multiplexing communication characteristics for a long range were estimated. The simulated and measured transmission isolations were more than 16.7dB and 13.5dB, respectively, for the distance of 125cm between the transmitting and receiving arrays. | |
