An isolator in RF engineering is an thin spacer placed between an antenna and an electromagnetically lossy object to improve radiation characteristics. Isolators are commonly used in RFID to overcome losses when RFID tags are placed on metallic objects. This set of notes provides an overview of HF (high-frequency) isolator operation using magnetic circuit theory. Notes for HF Isolators
UHF Isolators for RFID
An isolator in RF engineering is an thin spacer placed between an antenna and an electromagnetically lossy object to improve radiation characteristics. Isolators are commonly used in RFID to overcome losses when RFID tags are placed on metallic objects. This set of notes provides an overview of UHF (Ultra-high-frequency) and microwave isolator operation. Notes on UHF Isolators
EJECT! The Electronic Journal of Extemporaneous Contributions and Topics
After 15 years, a research program like the GTPG builds up numerous writings and contributions that never see the light of day. These are half-finished manuscripts, abandoned notes, snippets of unfunded proposals, and other writing projects that never saw the light of day. As a service to a small handful of people around the world, we at the GTPG hereby launch the newest online journal: EJECT: The Electronic Journal of Extemporaneous Contributions and Topics. When readership, impact factor, citations, and prestige do not matter; when only the love of a topic is enough to justify dissemination, EJECT! Click [EJECT!] to browse archives.
