Keroro and his friends are full of schemes to conquer the Earth, from training soldiers through karaoke to exploiting human reliance on cows to creating the perfect invasion environment with rain dolls! Will these frogs finally finish their fantastic plans? Not if the Hinata family can help it! Are Natsumi and Fuyuki really safe from the galactic green gang? -- VIZ Media
Sgt. Keroro, a frog-like alien, and his special-forces invasion team, are cut off from their planet and take refuge with the Hinata family, where they are watched by two children, Fuyuki and Natsum, as they plot to take over the Earth. Original.
The Eternal Question: Why haven't the Keron Troops been able to invade Pokopen? The Eternal Answer: They have lacked the frog-power to do so! Keroro's next scheme is mighty brilliant, even if he does think so himself! With Kururu's invention in his slimy hands, he hops to the zoo to recruit animals to join his platoon. The plan: Use Kururu's diabolical machine to turn any animal into human form! Is there no stopping this high-handed, web-footed wonder? -- VIZ Media
After Sgt. Keroro blew his cover and lost his top-secret weapon, the frog-like alien has been cut off from the homeworld. To make matters worse, he's lost communications with the rest of his platoon. Now he has taken cover in the Hinata family household, where in exchange for doing his share of the chores, he gets his own room from which to secretly devise new plans of world domination! -- VIZ Media
Since it was first published in 1995, Photonic Crystals has remained the definitive text for both undergraduates and researchers on photonic band-gap materials and their use in controlling the propagation of light. This newly expanded and revised edition covers the latest developments in the field, providing the most up-to-date, concise, and comprehensive book available on these novel materials and their applications. Starting from Maxwell's equations and Fourier analysis, the authors develop the theoretical tools of photonics using principles of linear algebra and symmetry, emphasizing analogies with traditional solid-state physics and quantum theory. They then investigate the unique phenomena that take place within photonic crystals at defect sites and surfaces, from one to three dimensions. This new edition includes entirely new chapters describing important hybrid structures that use band gaps or periodicity only in some directions: periodic waveguides, photonic-crystal slabs, and photonic-crystal fibers. The authors demonstrate how the capabilities of photonic crystals to localize light can be put to work in devices such as filters and splitters. A new appendix provides an overview of computational methods for electromagnetism. Existing chapters have been considerably updated and expanded to include many new three-dimensional photonic crystals, an extensive tutorial on device design using temporal coupled-mode theory, discussions of diffraction and refraction at crystal interfaces, and more. Richly illustrated and accessibly written, Photonic Crystals is an indispensable resource for students and researchers. Extensively revised and expanded Features improved graphics throughout Includes new chapters on photonic-crystal fibers and combined index-and band-gap-guiding Provides an introduction to coupled-mode theory as a powerful tool for device design Covers many new topics, including omnidirectional reflection, anomalous refraction and diffraction, computational photonics, and much more.
Follows the attempts of a platoon of frog-like alien invaders to conquer Earth. Sergeant Keroro, the titular character, is the leader of the platoon, but is at the mercy of a human family of three.
It's the dawn of a new school year for Fuyuki Hinata. As if the stress of starting junior high wasn't enough, he must also deal with Sgt. Keroro, the froglike alien with apocalyptic intentions freeloading in his attic. But if Fuyuki though the sergeant was a handful, wait until he gets a load of his subordinates! Keroro's gun-crazy cronies have started to surface, and not all of them agree with the way that he's been running the invasion! -- VIZ Media
While messing around with the Kero Ball, Fuyuki accidentally makes contact with Planet QQ--a planet of swindlers that has its greedy eyes set on Keroro. The reason? They want o-n-e b-i-l-l-i-o-n Q's from a penniless Keroro! Will he be able to dupe them into taking Natsumi as payment? Later, a ski holiday with the Hinata kids and Keroro and his gang turns into a Snow Beauty contest...with a Gundam prize! Can you say Pokopen's Next Top Model? April 1st is around the corner, so watch out for being made a fool. It's enough madness and mayhem to make Keroro want to play with dolls! -- VIZ Media
