“…However, the measured central frequency (4.75 GHz) is lower by approximately 1.2% than the simulated one (4.8 GHz). This shift can be attributed to fabrication tolerances, connectors, and the substrate properties [27][28][29][30][31]. The measured return loss is below −36 dB, and the measured insertion loss, at each branch, is approximately −3.2 dB at the central frequency.…”

“…The proposed mixer takes advantage of the aperiodic spatially varying structures which are capable of providing a variety of electromagnetic responses that are unattainable by uniform structures. Such structures may be used for the realization of highly efficient electromagnetic systems [50]- [64]. Fig.…”

The ever-increasing demand for high data rate wireless systems has led to a crowded electromagnetic spectrum. This demand has successively spurred the development of versatile microwave and millimeter-wave integrated components possessing high selectivity, multi-functionalities and enhanced efficiency. These components require a class of nonreciprocal structures endowed with extra functionalities, e.g., frequency generation, wave amplification and full-duplex communication. Space-time (ST) modulation has been shown to be a perfect candidate for high data transmission given its extraordinary capability for electromagnetic wave engineering. Spacetime-modulated (STM) media are dynamic and directional electromagnetic structures whose constitutive parameters vary in both space and time. Recently, STM media have received substantial attention in the scientific and engineering communities. The unique and exotic properties of STM media have led to the development of original physics concepts, and novel devices in acoustics, microwave, terahertz and optic areas. STM media were initially studied in the context of traveling wave parametric amplifiers in the 50s and 60s [1]- [6]. In that era, magnet-based nonreciprocity was the dominant approach to the realization of isolators, circulators and other nonreciprocal systems. However, magnet-based nonreciprocity is plagued with bulkiness, nonintegrability, heaviness and incompatibility with high frequency techniques.Recently, ST modulation has experienced a surge in scientific attention thanks to its extraordinary and unique nonreciprocity. It eliminates issues of conventional nonreciprocity techniques, such as bulkiness, heaviness and incompatibility with integrated circuit technology associated with magnetbased nonreciprocity, power restrictions of nonlinear-based nonreciprocity, and frequency limitations and low power handling of transistor-based nonreciprocity. It provides asymmetric interband photonic transitions [7]-[14], subluminal and superluminal phase velocities, and asymmetric dispersion diagrams [4], [11], [13], [14], and holds potential for energy accumulation [15]. Various enhanced-efficiency magnet-free microwave and optical components have been recently realized by taking advantage of the unique properties of ST modulation, including isolators [9], [11], [16]-[19], circulators [20]-[23],

A non-uniform C-section phaser is introduced as a powerful approach to enhance the design flexibility of uniform phasers. Moreover, an efficient synthesis technique is provided to design such phasers. Two design examples are presented. The first example is a single non-uniform C-section phaser. The second one is a cascaded double non-uniform C-section phaser featuring larger group delay swing and bandwidth, and hence higher resolution in Radio Analog Signal Processing (R-ASP).
