It eliminates the constraints of narrow bandwidth associated with traditional filter synthesis method. A set of three universal lumped LC circuit topologies are proposed to achieve arbitrary bandwidth, arbitrary order, and different distributions of N TZs. Additionally, we introduce an innovative approach to simultaneously extract components from both sides of the circuit during lumped LC circuit synthesis, which reduces accumulated numerical errors and improves the design speed. Several filters with the same 50–70 GHz passband but different TZs distributions, and an ultra-wideband filter from 30–90 GHz are successfully synthesized using the proposed circuit topologies and extraction method. Our proposed method can also be extended to design filtering impedance transformers for on-chip systems that surpasses the traditional RF design flow using 50 Ω interface and offers the combined benefits of component reduction and minimized system loss. Using the proposed design methodology, we fabricated a 90-nm SiGe BiCMOS on-chip filter which exhibits a low insertion loss of 1.5 dB at 59.16 GHz and a fractional bandwidth of 34%, achieving one of the best reported loss performances among silicon integrated filters to date. This research contributes to low-loss on-chip filter design methodology for universal design specifications and offers a design tool that can achieve high design speed and desired performance, enabling the promise of on-chip filter synthesis for emerging wireless technologies.","PeriodicalId":93296,"journal":{"name":"IEEE journal of microwaves","volume":"5 2","pages":"487-502"},"PeriodicalIF":6.9,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10892641","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This capability is particularly advantageous in challenging environments, where optical imaging techniques struggle. We present a novel approach to inverse rendering for near-field MIMO radar systems, aimed at reconstructing material properties such as surface roughness, dielectric constants, and conductivity from radar and ground-truth mesh data, for example obtained from multi-view stereo. Drawing inspiration from physically based rendering techniques in computer graphics, we formalize an advanced inverse rendering algorithm that integrates electromagnetic wave propagation models directly into the optimization process. To avoid bias from conventional radar image reconstruction algorithms in the optimization process, we directly derive gradients from raw radar outputs, resulting in more accurate material characterization. We validate our approach through extensive experiments on both synthetic and real radar datasets, demonstrating its effectiveness in a multitude of scenarios.","PeriodicalId":93296,"journal":{"name":"IEEE journal of microwaves","volume":"5 2","pages":"356-372"},"PeriodicalIF":6.9,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10892639","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143655011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed LPD link was tested in an indoor environment using an over-the-air (OTA) network. The transmitter and receiver communicate asynchronously and perform real-time modulation and demodulation. Importantly, the transmitter software minimizes memory usage, operational cost, and computationally-costly resampling is avoided. The receiver software acquires and tracks the transmitted waveform using parallel processing for speed, and uses multiple-layers for error detection to reduce computational resources. Further, the receiver's acquisition and tracking operations were profiled, and bottlenecks were removed by replacing slow calculations and algorithms to achieve faster sampling rates. This novel software design achieves significantly faster sampling rates, on the order of six times as compared to similar research. As a result, wider bandwidths and longer spreading codes are achieved to increase LPD characteristics. The asynchronous operation expands the system's usability to areas that are denied, degraded, or contested.","PeriodicalId":93296,"journal":{"name":"IEEE journal of microwaves","volume":"5 2","pages":"333-343"},"PeriodicalIF":6.9,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10854810","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the limited isolation of the coupler, the TX signal leaking into the RX significantly degrades the performance of the monostatic doppler radar. This paper presents the design of an ultra-compact impedance tuner (IT) which is connected to the lumped Rat-Race coupler to minimize the TX to RX leakage signal. The IT offers 5-bit phase control and 8-bit magnitude control via the Serial Peripheral Interface (SPI); moreover, it uses SiGe transistors in reverse saturation to enhance the impedance tuning performance. The size of the IT is only 0.04 mm<sup>2</sup> and its power consumption is 4 mW at 3.3V power supply. A two-channel 60 GHz monostatic doppler phased array radar chip has been designed and fabricated in 130 nm SiGe BiCMOS technology for vital signs monitoring application. The measured TX to RX isolation due to the Rat-Race coupler is 22 dB; moreover, IT provides the additional isolation of 27 dB, giving total TX to RX isolation of 49 dB at 60 GHz. The design, simulation and measurements of the IT and its measured leakage cancellation performance is reported in this paper.","PeriodicalId":93296,"journal":{"name":"IEEE journal of microwaves","volume":"5 1","pages":"84-95"},"PeriodicalIF":6.9,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10841826","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Throughout his very varied career, he always emphasized two things: the first he attributes to his mother's teaching - the great power of connecting individuals together to solve problems rather than trying to lead them to a solution, and the second – which is all his own – the fortitude to take on and stick with challenges that seemed daunting to others.

Towards that end, we are making major changes to our internal Editorial Board structure and paper screening methods. We will continue to focus on broad-appeal articles and cross-disciplinary topics that cover the entire range of microwave techniques and applications, and especially those subjects that breach traditional boundaries between engineering and science. We will also continue to bring you special editorial features on a regular basis, including this month's Microwave Pioneer article on UCLA's Mau-Chung Frank Chang. As our paper queue has expanded, we have decided to move to bimonthly, rather than quarterly issue releases. We hope this will reduce our paper queue and decrease the time between article submission and final issue-paginated release. Our January issue content includes 19 regular papers spanning topics that include wearable smart skins, batteryless IoT devices, astronaut hand gesture recognition, THz chiral structures, and metamaterial transmitarrays. We also bring you more than our usual quantity of the more core microwave filter, transmission line, antennas, and waveguide component papers, and a couple of papers on radar instruments and techniques.","PeriodicalId":93296,"journal":{"name":"IEEE journal of microwaves","volume":"5 1","pages":"3-13"},"PeriodicalIF":6.9,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10841824","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
