1. A radiator for terahertz electromagnetic radiation, comprising:
one or more radiator units each respectively comprising:
an oscillator arrangement operable to generate third harmonic power, the oscillator arrangement comprising:
a first oscillator operable to generate third harmonic power;
a second oscillator operable to generate third harmonic power; and
a coupler electrically coupling the first oscillator and the second oscillator; wherein the coupler comprises an even-mode-shorted coupler for enabling or sustaining an out-of-phase coupling mode between the first oscillator and the second oscillator; and
a patch antenna arrangement operably coupled with the oscillator arrangement for radiating terahertz electromagnetic radiation based on the generated third harmonic power.
