Reducing the radar cross section (RCS) is important to suppress radio wave interference. Many radar absorbent material (RAM) have been investigated according to performance requirements. This paper presents the RCS reduction characteristics of RAM composed of dielectric materials for 3 GHz. The optimum values of dielectric substance condition to design flat layer RAM are investigated. Moreover, RCS...
Thin wave absorbers composed of a periodic structure of metal patches have been investigated in order to reduce the radar cross section (RCS). To achieve stable operation for absorbing frequency at oblique incident angles, a high value of permittivity of the substrate or a very thin substrate are required. This paper presents the RCS reduction characteristics of a metasurface absorber with 0.1-mm...
Radio-frequency identification (RFID) systems have been employed for managing items in the closed spaces of construction machinery. In this paper, two horizontal polarization antennas, including a loop antenna and monopole antenna, are employed in an RFID system to investigate the radio transmission characteristics in a closed space.
A simplified method for measuring the specific absorption rate (SAR) is required in order to limit the spatial-average SAR for mobile devices in Japan. In this paper, a simplified SAR measurement method involving the use of a flat-plane lightweight phantom composed of a radio wave absorber is proposed. The utility of the lightweight phantom and the feasibility of using the proposed measurement method...
