Mutual Coupling, part 1

Mutual coupling, by its nature, is the near-field phenomenon and primarily depends on each element near-field structure, their relative to wavelength inter-element spacing, mutual orientation, and loading. Click on image to learn more.

Chapter 1 Dimensional Analysis, Vector Differential Operators, and Electrostatic

To boost the flavor of electromagnetics, we accompanied many problems with short Matlab code acting as a calculator and result illustrator. We completely ignored the description of algorithms behind the codes because they are often quite complicated and required ample, very sophisticated as well abstract mathematical specifics poorly helping to understand the physical picture. Such approach let us shift the focus from the often emasculated and practically fruitless problems to more complicated but close to practical tasks. We hope that it helps to visualize typically invisible EM fields and stimulate in-depth analysis and following discussion of the fundamental principles. Projecting images onto a big screen, the lectures may organize whole class conversation making the audience to be more engaged.

Deicing Graphene Nanoribbon Heating Layers

Ice-elimination systems are very common in large radio-frequency (RF) structures. They can be classified as either passive antiicing films (preventing the accumulation of ice) or active deicing devices (removing ice after accumulation). A typical application of an icing protection system is in radomes. Radomes are protecting shells or covers for radar instruments in aviation and marine environments. The radomes are subject to hostile environments, such as high winds containing sand, rain, hailstones, and saltwater, over wide temperature variations. Explosive pressure blasts can also take place nearby the radomes. Thus, radome deicing conductive films must be extremely tough with good adhesiveness to the heated surface. In addition, these deicing structures must not compromise the reliability of the original RF system, which, in the case of radome applications, means that the deicing film must be predominately transparent to RF radiation at any polarization with minimal impact on the antenna scan performance. It is desirable that this film be lightweight and low-cost, with physical characteristics that allow it to cover large curved surface areas.
