These cups are made up of aluminum and air acts as a dielectric material. Applications of Adjustable Capacitors: In coupling circuit in radio receivers. In tuning circuits for fine-tuning. #3 Variable Capacitors Image: Amazon The capacitors whose capacitance value can be varied continuously are called variable capacitors.
19.5 Capacitors and Dielectrics
A capacitor is a device used to store electric charge. Capacitors have applications ranging from filtering static out of radio reception to energy storage in heart defibrillators. …
Capacitors Basics
For example, if a 2-V battery is placed across a 10uF capacitor, current will flow until 20 uС has accumulated on the capacitor plates. Capacitors, ... In 1957, H. Becker invented electric double-layer capacitors, now known as supercapacitors, with a patent for a "Low voltage electrolytic capacitor with porous carbon electrodes." ...

Chapter 5 Capacitance and Dielectrics
Capacitors have many important applications in electronics. Some examples include storing electric potential energy, delaying voltage changes when coupled with
How to place decoupling capacitor in four-layer PCB?
Next comes whether should be placed at TOP or BOTTOM? the answer is decap must be placed close to the power plane, so that it can easily tap power can deliver to IC. Example: if Layer 2 from TOP is power plane place IC on TOP layer, if Layer 3 is power plane from TOP, place IC at the bottom layer.This point is only valid for asymmetrical PCB ...
PCB Layout Guidelines for Decoupling and Bypassing Capacitors
In a four-layer PCB, the top and bottom layers are component/signal layers, and the inner layers are the power and ground plane layers. ... Based on the principle of decoupling capacitors, we can correctly place the decoupling capacitor at the right location of the PCB layout to gain the optimal performance. The diagram below shows the two ...
Electronics/Capacitors
Super capacitors (Double-layer capacitors)—US$ 0.3 billion (2%); and; Others like silver mica and vacuum capacitors—US$ 0.7 billion (3%). All other capacitor types are negligible in terms of value and quantity compared with the above types. ... With the same dimensions this one could place twice the parallel-plate area inside. This ...

I''m using 0.01 uF decoupling capacitors in a 0805 package, on each V cc /GND pair of my CPLDs.So, around eight capacitors in total). I find it a bit easier to route the board if the decoupling capacitors are placed on the bottom layer and connected to the V cc and GND pins of the CPLD/MCU using vias.. Is this a good practice?
18.5 Capacitors and Dielectrics
A capacitor is an arrangement of objects that, by virtue of their geometry, can store energy an electric field. Various real capacitors are shown in Figure 18.29. They are usually made from conducting plates or sheets that are separated by an insulating material. They can be flat or rolled up or have other geometries.

Electrochemical Double Layer Capacitors | SpringerLink
An electrical double layer capacitor is used to compensate for electricity until another source is connected. The electrical double-layer capacitors utilized in energy fluctuation sources are known as energy equalization. Some power plants generate electricity using green energy, which is subject to natural changes.
Capacitor | Definition, Function, & Facts | Britannica
capacitor, device for storing electrical energy, consisting of two conductors in close proximity and insulated from each other. A simple example of such a storage device is the parallel-plate capacitor. If …

At least for this capacitor you seem to be able to place it on the top layer. If you would place it there at the same coordinates you would shorten the distance between cap and IC pins by at least 80% (you also have to calculate the PCB''s thickness). I would definitely try to do so. You can even move it a bit closer.
