This communication defines a figure of merit for multiband antennas that gives an objective quantification of the similarities between radiation patterns at the different antenna operating bands.

Fig.2 Amplifier under test. Amplifiers can operate in classes A, B, AB, C, D, E and F [2]. We tested class A amplifier made by „Microwave Power Devices“, Model: LWA 4690-1/1837, based on bipolar devices (Fig.2). Usually, 1dB compression point, gain and two-tone third-order intercept point are measured as the amplifier figure of merit. As specified by manufacturer, the frequency range of the amp...

Many promising approaches to fault-tolerant quantum computation require repeated nondemolition (QND) readout of binary observables such as bits (qubits). A commonly used figure merit for performance is the error rate assignment in a single repetition. However, it known that this insufficient. Indeed, real-world outcomes are typically analog instead binary. Binary therefore discards important in...
