Description
ここで、κは誘電材料40の誘電率、ε0は、約8.85×10−12C2/N・m2の誘電定数(Cはクーロン、Nはニュートン、mはメートル)、Aoverlap15−−25は電極15,25間の重なり部の面積、Y15−−25は、電極15,25間のギャップである。更に詳細に電極15と25の間の重複Aoverlap15−−25の面積を表すために、電極25上の点A、B、C、D、EおよびFが、図2に示されている。電極15,25間の重なり部の面積は、線分AB(バー)、BC(バー)、CD(バー)、DE(バー)、EF(バー)の合計に、図1に示した厚さX1を掛けることで与えられる。つまり、以下のようになる。
2つの電極(例えば電極25,45)のプレート間キャパシタンスC25−−45は、電極25の面積A25を、電極25と下にある次の電極45との間のギャップX2で割った値に比例する。電極25の面積A25を説明するために、2点以上G,Hが図2に定義されている。このように、電極25の面積A25は、線分AB(バー)、BC(バー)、CD(バー)、DE(バー)、EF(バー)、FG(バー)、GH(バー)およびHA(バー)に囲まれた面積として定義される。図1および2に示される従来のコーム式のコンデンサ10の注目すべき特徴は、ストリップ(例えば電極15のストリップ20および電極25のストリップ30,35)が直線状であるという点にある。
ここで、κは誘電材料115の誘電率、ε0は、約8.85×10−12C2/N・m2の誘電定数、A70−−75は電極70,75間の重なり部の面積、Y15−−25は、電極70,75間のギャップである。更に詳細に電極70と75の間の重複Aoverlap75−−75の面積を表すために、電極25上の点A’、B’、C’、D’、E’およびF’が、図4に示されている。電極70と75間の重なり部の面積は、線分A’B’ (バー)、点B’と点C’間の円弧SB’C’、線分C’D’ (バー)、点D’と点E’間の円弧SD’E’および線分E’F’ (バー)の合計に、図3に示した厚さX3を掛けることによって得られる。すなわち、以下のようになる。
