Guest Editors' Introduction: Design and Testing of Millimeter-Wave/Subterahertz Circuits and Systems

The articles in thus special issue focus on millimeter-wave (mmwave)and subterahertz (sub-THz) circuits and systems. Recent advances in silicon technologies have opened up new opportunities for investigations into mmwave and sub-THz circuits and systems. These systems have enabled extremely high-data-rate communications. Hence, many applications like high-definition media transfer, wireless network-on-chip (NoC), and highfrequency radar, have evolved to incorporate these technologies.
