<p>A transducer suitable for generating signals in the terahertz region has a resonant cavity (4) with apertures (6) aligned with a cold cathode source (2) being a field emitter array. The resonant cavity (4) consists of an inner cylindrical region (8) and an outer toroid region (9) that includes a slot antenna (11). To achieve signal generation in the terahertz region, the cavity (4) is fabricated using an etched polymeric material.</p> |
