Summary
We introduce a modular electromagnetic modeling method for large electromagnetic band-gap (EBG) structures. This technique efficiently designs devices by embedding domains, speeding up analysis for applications like EBG power splitters.
Area of Science:
- Electromagnetics
- Computational Electromagnetics
- Applied Physics
Background:
- Finite electromagnetic band-gap (EBG) structures are crucial in modern electromagnetic devices.
- Modeling large EBG structures poses significant computational challenges.
- Efficient design methodologies are needed for complex EBG applications.
Purpose of the Study:
- To propose a novel modular electromagnetic modeling procedure for large finite EBG structures.
- To develop a diakoptic method for efficient domain decomposition and analysis.
- To accelerate the design process of EBG devices through domain embedding.
Main Methods:
- Linear embedding via Green's operators, a diakoptic method based on the Huygens-Schelkunoff principle.
- Characterization of enclosed domains using equivalent boundary current sources as multiport systems.
- Cascade of embedding steps to combine reusable domains and transfer environmental sources.
Main Results:
- The proposed method enables modular modeling of large finite EBG structures.
- Equivalent sources of the environment are transferred to the boundary of designated domains for faster design.
- A two-stage optimization process was successfully applied to design an EBG power splitter.
Conclusions:

02:35Band Theory
When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

01:30Plane Electromagnetic Waves I
The existence of combined electric and magnetic fields that propagate through space as electromagnetic (EM) waves is the most significant prediction of Maxwell's equations. As Maxwell's equations hold in free space, the predicted electromagnetic waves do not require a medium for their propagation. An EM wave comprises an electric field, defined as the force per charge on a stationary charge, and a magnetic field, which is the force per charge on a moving charge.
The EM field is assumed to be a...

01:28Standing Waves in a Cavity
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:
01:01Energy Bands in Solids
Isolated atoms have discrete energy levels that are well described by the Bohr model. And, it quantifies the energy of an electron in a hydrogen atom as En. Higher quantum numbers 'n' yield less negative, closer electron energy levels.
Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states that no two...

01:27Extended Versions of Green’s Theorem
Green’s Theorem connects the circulation of a vector field around a closed curve with the behavior of the field across the region enclosed by that curve. It provides a way to replace a line integral around a boundary with a double integral over the interior region, making it especially useful in plane geometry, fluid flow, and vector calculus.Although Green’s Theorem is often introduced using simple regions without gaps, it can also be applied to regions made from several simple parts. This...
01:26Vector Forms of Green’s Theorem
The study of fluid motion often involves understanding how local rotational behavior relates to global circulation. In the context of a pond with pollutants, direct measurement of water movement along an irregular shoreline can be impractical. Green’s Theorem in vector form provides an alternative by relating the circulation around a closed boundary to properties of the flow within the enclosed region.Measurements of water velocity at different points define a continuous vector field that...
