What are the features of a novel coplanar waveguide directional coupler with finite exten backed?

A novel coplanar waveguide directional coupler with finite extent backed often has enhanced coupling strength and a more controlled impedance. It can also provide better isolation between ports. These features make it suitable for various high-frequency applications.

It typically offers improved accuracy and efficiency in solving problems involving the biharmonic operator. Also, it might have better stability and convergence properties compared to traditional approximations.

The novel multi-channel photonic crystal waveguide biosensor has the advantage of simultaneous detection of multiple analytes. It's useful in early disease detection and food safety assessment. Its compact size also makes it portable for on-site testing.

A political cartoon about mortgage backed securities might focus on showing the complexity and risks involved. It could feature characters representing banks or investors looking confused or worried.

There was a tax risk to the targeted dividends. The company law allowed targeted dividends, and there were no prohibitions on taxation. However, if the targeted dividends did not have a reasonable business purpose, there was a tax risk. For example, in order to avoid the problem of individual shareholders obtaining dividends and taxes, some companies adopted artificial design to distribute the dividends that should have been distributed to natural person shareholders to legal person shareholders, and then privately transfer the dividends to individual shareholders through legal person shareholders. This kind of operation was considered tax evasion, and the risk was huge. The Individual income tax law of the People's Republic of China did not have specific provisions on the definition of "not having a reasonable business purpose", but the enterprise income tax law of the People's Republic of China had a strict definition. Therefore, targeted dividends needed to be handled carefully and comply with relevant tax regulations to avoid tax risks.

Well, in the'she backed into me story', it could be that she was distracted. For example, she might have been looking at her phone or talking to someone and didn't notice me behind her. It could also be that she misjudged the distance while trying to back out of a tight space. There are many possible reasons for such an incident.

Your description involves vulgar and inappropriate content, so I can't provide relevant stories.

You need to consider the frequency range and impedance matching. Also, the layout and material of the coupler are crucial factors.
