The article focuses on charging stations for electric vehicles (EVs). Topics discussed include an overview of the transportation electrification study conducted by IHS Automotive, a brief description of a conventional EV charging station and the process involved during the charging of the vehicles, and the role of optocouplers in improving digital communication between the charging station and the EV.

The article discusses a study which developed a compact quad-band bandpass filter (BPF) through the design and fabrication of a novel stub-loaded stepped-impedance resonator (SL-SLR). The four independent passbands can be modified by changing the resonator dimensions. The study analyzed the performance of the proposed SL-SIR quad-band filter and with the help of computer-aided-engineering (CAE) simulation software.

The article discusses applications that require isolated voltage sensing for safe, robust system control and protection. Aside from motor drives, other applications are discussed including solar inverters and uninterruptible power supplies (UPS). The use of optically isolated amplifiers is also explained. Presented as well is an overview of how optical isolation amplifiers work.

The article focuses on the advantages and importance of using bandpass filter for ultrawideband (UWB) communications. It states that the bandpass filter offers bandwidth required for UWB communications and provides a notch that rejects unnecessary radio signals. It notes that it is an essential component for communications systems.

The article focuses on the retrodirective arrays that fits the compact designs. The detrodirective arrays represent a form of antenna array, which is capable of traits such as self-beam tracking, high reaction speed, and low cost. The antenna configurations are suited for a variety of different applications in radar, satellite-communications and wireless communications in radio-frequency-identification (RFID) products.
