Èske w gen deja modle, manifaktire ak karakterize yon sifas ki vag Lüneburg lantiy ak Omni-direksyon absòbe, ekip nou an nan chèchè kounye a ta vle konprann fondamantal yo nan vag sifas nan ruptur, limit, domaj ak bor. Pandan ke rad vag sifas ka ede yo envante diminye simen soti nan domaj sa yo ak yon pafè absorbers vag sifas ta konplètman evite vle gaye, yo operasyon an nan antèn vag ki gen fuit / sifas ki baze sou kondisyon de efikas soti-kouti nan enèji vag sifas yo. Kontwòl nan direksyon ak ang la gaye siyal la gaye se nan gwo enpòtans pou itil pèfòmans aparèy.

Having already modelled, manufactured and characterised a surface wave Luneburg lens and omni-direction absorber, our team of researchers now wish to understand the fundamentals of surface waves at discontinuities, boundaries, defects and edges. While surface wave cloaks can help be devised to reduce scattering from these defects and a perfect surface wave absorbers would completely avoid unwanted scatter, the operation of leaky / surface wave antennas are based on the requirement of efficient out-coupling of surface wave energy. The control of the directionality and angle spread of the scattered signal is of great relevance for useful device performance.
