Summary: The Maxwell-Lindblad transmission line (MLT) equations are introduced as a model for hybrid photonic and microwave-electronic quantum devices. The hybrid concept allows for high-bandwidth photodetectors and modulators, and can be extended to quantum-engineered lasers for improved short-pulse and frequency comb operation. The MLT model provides a theoretical description for hybrid quantum devices, enabling realistic device simulations in agreement with experimental data.

Summary: Organic electronic materials have played a significant role in the development of various technologies in the past two decades. Among them, organic mixed ion-electronic conductors (OMIECs) have gained renewed interest and are regarded as key drivers in the fields of bioelectronics, energy storage, and neuromorphic computing. This study demonstrates the use of solution-processed intrinsic OMIECs to actively tune the properties of metamaterial-inspired microwave devices, showcasing the substantial potential of OMIEC-based metadevices in autonomous bioelectronics and reconfigurable microwave optics.

Summary: This article investigates what makes a software development method agile. Through a large-scale international survey and data analysis, the findings suggest that although only a small number of participants operate their projects in a purely traditional or agile manner, most project disciplines and practices show a trend towards increasing degrees of agility. It is concluded that agility cannot be solely defined at the process level and additional factors need to be taken into account when implementing or improving agility in a software company.

Summary: In this article, a generalized statistical theory is derived to predict the occurrence of multipactors in high-power vacuum microwave devices. The theory is capable of predicting multipactor occurrences in devices with complex geometric cavities and arbitrary excitations. The results obtained from the theory were consistent with previously reported experiments and simulations and explained three special phenomena that occur during multipactors, validating the accuracy and effectiveness of the proposed solution.

Summary: In this study, an equivalent circuit analysis was conducted for the dual side-coupled cavities (DSCCs), which can be used as RF interaction structures in high power microwave devices and linear accelerators. The analysis determined the equivalent shunt capacitance per unit length and series inductance per unit length for TM01 mode operation. The phase velocity and characteristic impedance of the DSCC were calculated using these equivalent circuit parameters, and the dispersion behavior of the DSCC was also explored. The analysis was validated through electromagnetic simulations.

Summary: MW dielectric ceramics are essential for electronic components in wireless communication systems, but traditional high-temperature sintering methods limit their integration with other materials. Cold sintering, a process at lower temperatures, offers energy-efficient densification and better compatibility with diverse materials. Current research focuses on improving cold-sintered MW materials and devices, addressing challenges like unclear mechanisms and poor mechanical properties.

Summary: Recently, an all-optical method for generation of multiband chirp-rate-tunable microwave waveforms is proposed and demonstrated on an all-fiber architecture. The experiment achieves triangular optical chirp microwave waveforms with bandwidth above 0.45 GHz and chirp rate reaching 0.9 GHz/ms. The reconfigurability is also demonstrated by adjusting the control signal. This all-optical approach provides a technical basis for compact, multi-band reconfigurable microwave photonics transmission and reception systems.

Summary: This letter introduces a new surrogate-based multiphysics optimization technique for microwave devices incorporating artificial neural networks (ANNs) and a trust-region algorithm. By using a parallel data generation technique and recalculating the range of the ANN surrogate model at each optimization iteration, the values of design parameters are effectively updated towards the optimal solution, leading to faster convergence.
