“…Another challenge is to perfectly choose a numerical method of simulation which guarantees an easy and fast analysis of the electromagnetic problem. In the literature, transmission line matrix (TLM) and transmission matrix method (TMM) methods [17–19] are specially used to analyze periodic lumped circuits. These methods have remarkable limits such as complex programing of the parameters of the periodic circuits which largely differs from one circuit to other and the problem of stability when manipulating very large circuits.…”

In this paper, we propose a novel study of zero-index materials (ZIM) based on lumped element circuits using a wave concept iterative method (WCIP). This method is well used to demonstrate the behavior of zero-index-based microwave applications. This type of metamaterial can maintain the amplitude and the phase of an electromagnetic wave to be constant through the ZIM region, which is an important property to design an in-phase power divider-combiner, enhance the directivity of an embedded source, channel electromagnetic waves without reflection at the interface between waveguides with different cross-sections, and control the transmission of electromagnetic wave by the adjustment of the permittivity of a dielectric defect coated by zero-index metamaterial. The numerical simulations using the WCIP method match the literature and commercial software simulator results.

The term “microwave circuits” is used to identify the electrical circuits used at microwave frequencies for performing signal‐processing functions such as amplification, frequency conversion, mixing, detection, phase shifting, filtering, and power dividing. By “microwave frequencies,” we refer to electromagnetic signals whose wavelength is in centimeters, roughly from 30 cm to 1 mm with the corresponding frequencies ranging from 1 GHz (GHz = 10 9 Hz) to 300 GHz. The frequency range from 30 to 300 GHz is also known as the millimeter‐wave band . Microwave frequencies present several interesting and unusual features not found in other portions of the electromagnetic frequency spectrum. These features make microwaves uniquely suitable for several useful applications in telecommunications, radar, industrial heating and sensors, wireless power transfer, and so on. The most common consumer application of microwaves is the domestic microwave oven used for food processing.
