Chapter 9 - One open loop, two stubs, and two infinite leads

Housni Al-Wahsh, Eman Abdel-Ghaffar, Abdellatif Akjouj, Madiha Amrani, Leonard Dobrzyński

The present system is constructed out of one open loop of length L, two stubs of length , and two infinite leads. It is shown that the transmission properties of such a system depend on its bulk states localized in the whole structure and on infinite bound in continuum (IBIC) states. These IBICs…
