“…At frequencies above 10 GHz, only special diodes made of compound semiconductor materials (such as modified barrier integrated diodes) may provide the appropriate sensitivity. Also, it has been shown that the traditionally accepted view of the electronic diodes as true square-law detectors at low power levels is correct only under restrictive conditions [18]. By way of contrast, at input voltages smaller than , the parabolic transfer function of the microdisk resonator results in a true square-law behavior independent of the external circuitry.…”

“…As mentioned in Section II, the electronic diode and microdisk photonic mixer can be compared by evaluating for the diode and for the microdisk photonic mixer. At low frequencies (below 5 GHz), typically A/V [9], [18], which is 100 times larger than for our LiNbO microdisk mixer and a photodetector with A/W. However, with increasing carrier frequency, the sensitivity of electronic diodes falls and its fabrication cost grows.…”

Abstract-Nonlinear optical modulation combined with simultaneous photonic and RF resonance in an LiNbO 3 microdisk modulator is used to create a self-homodyne photonic RF receiver. Carrier and sidebands are mixed in the optical domain, and the modulated optical signal is detected using a photodetector. The photodetector has a bandwidth matched to the baseband signal. It filters out the high-frequency components and generates the baseband photocurrent. Receiver operation is demonstrated by demodulating up to 100-Mb/s digital data from a 14.6-GHz carrier frequency without any high-speed electronic components. A bit error rate of 10 9 is measured for 10-Mb/s downconverted digital data at 15-dBm received RF power. Preliminary results of employing this photonic RF receiver in a short-distance -band wireless link demonstrate the potential of using high-quality optical microresonators in RF receiver applications.

of the RF-':Iarvesting system. The RF-Harvesting system IS divided Into the urnts: receiving antenna, the impedance transformation unit, the rectification unit and the load. To improve the efficiency the impedance of the receiving antenna has to be matched to the imput impedance of the rectifier circuit.Abstract-This paper presents a new method for rectifying low ambient radiation sources to supply autonomous measurement systems such as microsystems. An impedance transformation with high quality factor (Q) in front of a Schottky-Diode using a quartz resonator at 24 MHz is presented. In addition to an analytic computation and nonlinear simulation of the rectifier circuit with Advanced Design System (ADS) software, the circuit was built and the efficiency of the RF Energy Harvesting system was measured. The design has been optimized to achieve maximum sensitivity. The measurement results show a sensitivity of -30 dBm (1 p,W) for DC output voltage of 1 V and an efficiency of more than 22 %.

SUMMARYIn this paper, a novel method to efficiently calculate the power transfer efficiency of a wireless power transfer system in the radiative near-field is proposed. The technique allows repositioning of the antennas without large additional cost. It relies on a single simulation (or measurement) of the radiation pattern of the antennas used. Thanks to its high computational efficiency, it can be used in multi-transmitter and multi-receiver scenarios when there is no coupling between devices via the reactive near-field. Our method is applied to the latter to demonstrate its accuracy and computational efficiency.
