This paper proposes new reflectarray elements for dual-polarization and wideband use. These elements provide liner phase property with the same slope characteristics for dual polarization, thereby achieving the desirable reflection phase over wide frequency range. The usefulness of the proposed elements is verified by comparing between the calculated(More)
The axial forces are measured to derive an algorithm for the simultaneous measurement of external and internal forces of a parallel mechanism. We designed axial force sensors and evaluated their measurement accuracy. The external and internal forces are measured simultaneously using a real-time measurement system with RT Linux.
