A.
Hertzian waves
Hertzian waves are early experimentally demonstrated electromagnetic waves that confirmed James Clerk Maxwell’s theory of electromagnetism and paved the way for modern radio communication.
-
B.
Kennelly–Heaviside layer theory
Kennelly–Heaviside layer theory is an early 20th-century scientific model proposing the existence of a conductive layer in the upper atmosphere that reflects radio waves, helping to explain long-distance radio communication.
-
C.
Theory and Calculation of Alternating Current Phenomena
Theory and Calculation of Alternating Current Phenomena is a foundational electrical engineering text that systematically develops the mathematical analysis and practical design principles of alternating current (AC) circuits and machinery.
-
D.
IEEE Microwave Theory and Techniques Society
The IEEE Microwave Theory and Techniques Society is a professional society within IEEE focused on the advancement of microwave theory, techniques, and technologies in areas such as wireless communications, radar, and RF engineering.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
