Interaction accuracy and transparency of force feedback devices (FFDs) are crucial in applications like remote surgery, where high (FFA) ensures the safety delicate procedures. However, few studies have introduced calibration FFDs, especially addressing low FFA issue dynamic motions. This paper proposes a method closed-loop control (CLC) strategy for an FFD to enhance its FFA. Tailored models were developed by decoupling factors causing errors. The CLC was achieved modeling FFD's kinematics,...

A double-layer metamaterial absorber is proposed to suppress the mutual coupling within a circularly polarized (CP) four-element antenna array operating at Chinese Beidou navigation satellite system (BDS) B3 band, wherein four miniaturized patch elements are positioned in rotationally symmetric distribution. The single-feed element utilizes simultaneously thick air substrate widen achievable CP bandwidth, parasitic grounded strips reduce size occupation, and capacitive probe feed enhance...
