Gray objects have a uniform ability to absorb all parts of the electromagnetic spectrum. Colored objects behave in similar but more complex ways, which gives them a particular color in the visible range and may make them special in other ranges of the nonvisible spectrum. Take, for example, t...

Conclusion: In most centers, the radiation treatment of breast is realized with two tangential opposite beams, which usually are mirror beams, or in other words, the internal and external beam angles create an angle of 180˚{伪 + 尾 = 180˚}. This is a simple method, which provides a...
We shall also suppose that the radiation does not pass through the body; in other words, all radiation not reflected is completely absorbed. Then the quantity of radiation (63.20) must be balanced by the radiation emitted by the body itself in the same directions at the same frequencies. ...
Keeping in mind the simple relation between the far-zone field vectors and the far-zone power density, the normalized field and power patterns relate to each other as FP(θ,φ)=FE2(θ,φ). Radiation patterns are often plotted in decibels, where the angular function is FdB(θ,φ)= 10log...
High-index nanoparticles are known to support radiationless states called anapoles, where dipolar and toroidal moments interfere to inhibit scattering to the far field. In order to exploit the striking properties arising from these interference condition
A phrase so simple yet filled with meaningful words, a phrase that I try to abide by. Growing up in a small city in Syria, I had never imagined one day I would immigrate to the United States. But my father desired a better life for his family like many others before him. Coming ...

The discrete transfer radiation model (DTRM) is used for cases where the radiation emitted from a surface element in continuous and specified intervals of solid angles can be considered a single ray. Its advantages are that the model is relatively simple, capable of increasing accuracy with the ...
