Advance research in electromagnetic theory has been a fundamental key driver to push the frontier of biomedical technology. These studies include evaluation of health hazards of microwave field emission by ubiquitous wireless communication systems, interaction of electromagnetic waves with biological tissues and living systems, and also the therapeutic, diagnostic, and imaging applications of electromagnetic. Cancer detection using ultra-wideband signal, hyperthermia of tumours, healthcare informatics, and wireless bioimplants are some for the research topics using electromagnetic waves. Out of the accepted papers of this special issue, four papers will be highlighted below.

Electric field measurement of the living human body for biomedical applications: phase measurement of the electric field intensity” by I. Hieda and K. C. Nam illustrates a technique for conducting measurements inside the human body by applying a weak electric field at a radio frequency (RF). The method is simple, safe, cost-effective, and able to be used for biomedical applications.

Y. Chen et al. present “A feasibility study for microwave breast cancer detection using contrast-agent-loaded bacterial microbots.” The authors proposed a novel differential microwave imaging technique to simultaneously track multiple swarms of magnetotactic bacteria microbots that are injected into the breast to detect breast tumours.

Analysis and design of magnetic shielding system for breast cancer treatment with hyperthermia inductive heating” by C. Thongsopa and T. Thosdeekoraphat provides an analysis and design of rectangular magnetic shielding aperture system for breast cancer treatment with hyperthermia inductive heating.

J. Tak et al. present “Dual-band on-body repeater antenna for in-on-on WBAN applications.” This paper investigates an antenna for in-on-on wireless body area network applications, which was designed to communicate with implanted devices in the 5.8 GHz ISM band and to transmit the biological information received from the implanted devices to other on-body devices in the 2.45 GHz ISM band.
