In this method, efficiency is improved by tuning the resonance frequency at a value where kQ has a maximum. This is carried out by a terminating capacitor for the resonators. In this case, the resonance frequency is less than the self-resonance frequency. However, the capacitance of the tuning capacitor is small enough to ensure that both electric and magnetic coupling will contribute to power transmission. Applying the proposed method to two square 18 cm × 18 cm antidirectional spiral resonators at a spacing of 270 mm, the efficiency is increased to 20% compared with 13% at the SRF. Moreover, the proposed method desensitizes the power transfer efficiency to the nearby objects.]]>175803807524<![CDATA[Quasi-Deterministic Channel Model Parameters for a Data Center at 60 GHz]]>175808812739<![CDATA[AMC's Angular Stability Improvement Through the Introduction of Lumped Components]]>175813816358<![CDATA[High-Efficient Wideband Transmitarray Antenna]]>0^{2} has 22.3 dBi maximum gain at 10.3 GHz.
