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
