ELEX的一個目標是快速出版原創的同行評議的短文，這些短文涉及現代電子和電氣工程領域。可接受字段的邊界沒有嚴格界定，它們靈活變化以反映字段的趨勢。ELEX的范圍主要集中在設備和電路技術上。當前適當的主題包括：-集成光電子學（激光和光電子器件、硅光子學、平面光波電路、聚合物光學電路等）-光學硬件（光纖、微波光子學、光學互連、光子信號處理、光子集成與模塊、光學傳感等）-電磁理論-微波和毫米波器件、電路和模塊-THZ設備、電路和模塊-電子器件、電路和模塊（硅、復合半導體、有機和新型材料）-集成電路（存儲器、邏輯、模擬、射頻、傳感器）-動力裝置和電路-微型或納米機電系統-存儲電路和模塊-超導電子學-能量收集裝置、電路和模塊-電子顯示器用電路和模塊-電子儀表用電路和模塊-物聯網和生物醫學應用的裝置、電路和模塊

An aim of ELEX is rapid publication of original, peer-reviewed short papers that treat the field of modern electronics and electrical engineering. The boundaries of acceptable fields are not strictly delimited and they are flexibly varied to reflect trends of the fields. The scope of ELEX has mainly been focused on device and circuit technologies. Current appropriate topics include: - Integrated optoelectronics (lasers and optoelectronic devices, silicon photonics, planar lightwave circuits, polymer optical circuits, etc.) - Optical hardware (fiber optics, microwave photonics, optical interconnects, photonic signal processing, photonic integration and modules, optical sensing, etc.) - Electromagnetic theory - Microwave and millimeter-wave devices, circuits, and modules - THz devices, circuits and modules - Electron devices, circuits and modules (silicon, compound semiconductor, organic and novel materials) - Integrated circuits (memory, logic, analog, RF, sensor) - Power devices and circuits - Micro- or nano-electromechanical systems - Circuits and modules for storage - Superconducting electronics - Energy harvesting devices, circuits and modules - Circuits and modules for electronic displays - Circuits and modules for electronic instrumentation - Devices, circuits and modules for IoT and biomedical applications
