How the clue works
The whole thing defines Early Porsche development — VW BUG, an early Volkswagen, and VW owns Porsche. The "frontiers of UV waves" gives the letters at the border where the two words meet: the V finishing UV and the W beginning waves, making VW; then BUG is spyware (a hidden listening device), sitting underneath in this down clue thanks to "on".
