This　paper　presents　a　design　of　thin　and　broadband　non-magnetic　metamaterial　absorbers　using　circular　loop　shaped　resistive　frequency　selective　surfaces　(FSS).　A　straightforward　visual　graphic　representation　analysis　which　extends　the　microwave　impedance　matching　theory　into　wideband　metamaterial　absorbing　structure　design　is　carried　out　on　the　key　parameters　analysis　of　the　absorbers.　The　single　layer　absorber　is　analyzed.　Numerical　computing　results　are　in　good　agreement　with　the　analyzed　ones.　The　study　shows　that　visual　graphic　representation　analysis　could　greatly　decrease　the　range　of　variable.　The　visualization　method　is　simple　and　practicable　to　introduce　the　working　principles　of　the　wideband　non-magnetic　metamaterial　absorbing　structure　and　to　derive　the　best-suited　element　for　wideband　absorption.
