Ol teknikel as tingting na lus optimaisesen
As bilong lus
Bikpela samting em resistive loss (heat dissipation we i kamap long karent i ron long kondakta) na dielectric loss (polarisasen ifek bilong insulating materiel). Resistive loss i go antap wantaim 'square root' bilong 'frequency', na 'dielectric loss' i go antap wantaim 'frequency'.
Ol rot bilong mekim gutpela wok
Samting bilong Kondakta:Yusim multi-strand silva-plated kopa waia long daunim hevi bilong skin.
Insulesen:Yusim 'expanded polyethylene' o 'fluoroplastic' long daunim 'dielectric constant' na daunim 'energy absorption'.
Straksa bilong banisim:Silva-plet kopa tep + hai-density braiding i givim tupela kain banis long daunim 'electromagnetic interference'.
